  • 1. 

    The chemicals that produce instructions on each gene are:

    • A.

      Five bases

    • B.

      Five amino acids

    • C.

      Four bases

    • D.

      Four amino acids

    Correct Answer
    C. Four bases
    Explanation
    Genes are made up of DNA, which consists of sequences of four different bases: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases act as the chemical instructions that determine the genetic code. Therefore, the correct answer is "four bases."

    The full set of genes that is the instructions to make a living organism is called:

    • A.

      DNA

    • B.

      Genotype

    • C.

      Gamete

    • D.

      Genome

    Correct Answer
    D. Genome
    Explanation
    The term "genome" refers to the complete set of genes or genetic material present in an organism. It includes all the instructions required for the development, functioning, and reproduction of that organism. DNA, on the other hand, is the molecule that carries the genetic information within the genome. Genotype refers to the specific combination of genes an organism possesses, while gamete refers to the reproductive cells involved in sexual reproduction. Therefore, "genome" is the correct answer as it encompasses the entire set of genetic instructions.

  • 4. 

    What is formed when a sperm cell and an ovum fuse?

    • A.

      Zygote

    • B.

      Reproductive cell

    • C.

      Embryo

    • D.

      Fetus

    Correct Answer
    A. Zygote
    Explanation
    When a sperm cell and an ovum fuse, they form a zygote. The zygote is the initial stage of a new organism's development, resulting from the combination of genetic material from both parents. It is the first cell of a new individual and will undergo cell division to eventually develop into an embryo and then a fetus. The zygote contains all the genetic information necessary for the development of a new organism.

    Rate this question:

  • 5. 

    Because of cultural preferences, women have sometimes looked for ways to alter the sex of their embryos. Which of the following is true?

    • A.

      Eating hot foods can alter the sex of an embryo

    • B.

      Eating cold foods can alter the sex of an embryo

    • C.

      Sleeping on one side can alter the sex of an embryo

    • D.

      No post-conception diet or action can alter the sex of an embryo

    Correct Answer
    D. No post-conception diet or action can alter the sex of an embryo
    Explanation
    The correct answer is that no post-conception diet or action can alter the sex of an embryo. This means that regardless of what a woman eats or how she sleeps, it will not have any impact on the sex of the embryo. The sex of the embryo is determined by the genetic material provided by the parents at the time of conception. Cultural preferences or beliefs may lead some women to seek ways to alter the sex of their embryos, but scientifically, it is not possible.

    Rate this question:

  • 6. 

    If a zygote has the genes for "musical genius," which is true?

    • A.

      The zygote will become a person who is a musical genius

    • B.

      Nothing can prevent the development of a trait for musical genius

    • C.

      Additional genes and factors in the environment may result in the development of a trait for musical genius

    • D.

      Genotype equals phenotype

    Correct Answer
    C. Additional genes and factors in the environment may result in the development of a trait for musical genius
    Explanation
    The presence of genes for "musical genius" in a zygote does not guarantee that the individual will become a musical genius. The development of a trait is influenced by both genetic factors and environmental factors. Therefore, additional genes and factors in the environment may contribute to the development of a trait for musical genius. This means that other factors such as upbringing, education, and practice can also play a role in determining whether the individual will actually become a musical genius.

    Rate this question:

  • 7. 

    _____ refers to traits that are affected by many genes, and _____refers to traits that are influenced by many factors.

    • A.

      Polygenic; multigenic

    • B.

      Polygenic; multifactorial

    • C.

      Genetic; environmental

    • D.

      Multifactorial; polygenic

    Correct Answer
    B. Polygenic; multifactorial
    Explanation
    Polygenic traits are those that are influenced by multiple genes. This means that the phenotype of the trait is determined by the combined effects of many different genes. On the other hand, multifactorial traits are influenced by a variety of factors, including both genetic and environmental factors. Therefore, the correct answer is "Polygenic; multifactorial".

    Rate this question:

  • 8. 

    When a pair of alleles interact, the resulting phenotype reveals the influence of one allele more than that of the other allele. This pattern is called:

    • A.

      An additive gene pattern

    • B.

      A dominant-recessive pattern

    • C.

      An on-off switching pattern

    • D.

      A differentiation pattern

    Correct Answer
    B. A dominant-recessive pattern
    Explanation
    When a pair of alleles interact, the resulting phenotype reveals the influence of one allele more than that of the other allele. This pattern is called a dominant-recessive pattern. In this pattern, the dominant allele is expressed and determines the phenotype, while the recessive allele is masked and does not have a visible effect on the phenotype. This is a fundamental concept in genetics, where dominant alleles are represented by uppercase letters and recessive alleles by lowercase letters. This pattern helps explain why certain traits are more common in populations, as dominant alleles are more likely to be expressed and passed on to future generations.

  • 9. 

    Most recessive genes on a male's X chromosome are expressed because:

    • A.

      Alleles on the Y chromosome are always recessive to other alleles

    • B.

      Sex-linked disorders are always expressed

    • C.

      Males are more prone to genetic disorders

    • D.

      The X-linked allele is not paired with any allele on the Y chromosome

    Correct Answer
    D. The X-linked allele is not paired with any allele on the Y chromosome
    Explanation
    The correct answer is that the X-linked allele is not paired with any allele on the Y chromosome. This is because males have one X chromosome and one Y chromosome, while females have two X chromosomes. Therefore, any allele on the X chromosome in males does not have a corresponding allele on the Y chromosome to pair with, resulting in the expression of most recessive genes on the X chromosome.

    Monozygotic twins, Randy and Rowdy, originated from the same zygote and therefore have identical genes.  They have many similarities, but what explains the differences in their height, weight, and behavior?

    • A.

      They are not monozgotic twins, but rather dizygotic twins

    • B.

      The effects of nature and nurture are exactly the same for monozygotic twins

    • C.

      There is not an explanation for these differences

    • D.

      Something in one of the boy's environment affected his genes differently than his brother

    Correct Answer
    D. Something in one of the boy's environment affected his genes differently than his brother
    Explanation
    The differences in height, weight, and behavior between monozygotic twins Randy and Rowdy cannot be solely attributed to their genes since they share identical genes. Therefore, the most plausible explanation is that something in one of the boys' environment affected his genes differently than his brother. This suggests that external factors such as nutrition, lifestyle, or experiences might have influenced the expression of certain genes, leading to the observed differences in height, weight, and behavior.

    The process by which ova are surgically removed from a woman, and then mixed with sperm to produce a zygote, which then is inserted into the uterus, is called:

    • A.

      In vitro fertilization

    • B.

      Amniocentesis

    • C.

      Cloning

    • D.

      Stem cell research

    Correct Answer
    A. In vitro fertilization
    Explanation
    In vitro fertilization is the correct answer because it accurately describes the process of surgically removing ova from a woman, combining them with sperm to create a zygote, and then implanting the zygote into the uterus. This method is commonly used to assist couples with fertility issues and help them conceive a child. Amniocentesis is a different medical procedure used to collect amniotic fluid for genetic testing during pregnancy. Cloning and stem cell research are unrelated to the process of fertilization.

    Rate this question:

  • 12.

    • A.

      The mother to have high blood pressure and toxemia

    • B.

      Under-weight and premature babies

    • C.

      The babies to have higher rates of early death, disease, and disabilities

    • D.

      All of the answers are correct

    Correct Answer
    D. All of the answers are correct
    Explanation
    Multiple births from the implantation of more than one zygote can cause various complications for both the mother and the babies. The mother may experience high blood pressure and toxemia, which are conditions that can be harmful to her health. The babies born from multiple births are more likely to be underweight and premature, which can increase their risk of health issues and developmental delays. Additionally, multiple births are associated with higher rates of early death, disease, and disabilities in the babies. Therefore, all of the answers provided are correct in highlighting the potential consequences of multiple births.

    Schizophrenia is a result of:

    • A.

      Gene-gene interaction alone

    • B.

      Both gene-gene and gene-environment interaction

    • C.

      Gene-environment interaction alone

    • D.

      Poor parenting

    • E.

      Environment interaction alone

    Correct Answer
    B. Both gene-gene and gene-environment interaction
    Explanation
    Schizophrenia is believed to be a complex disorder that results from a combination of genetic and environmental factors. The answer "both gene-gene and gene-environment interaction" suggests that the development of schizophrenia involves interactions between multiple genes as well as interactions between genes and the environment. This means that both genetic predisposition and environmental triggers play a role in the manifestation of schizophrenia. It is important to note that poor parenting or environment alone is not considered the sole cause of schizophrenia, but rather factors that contribute to the overall risk.

      Inherited genes express a person's behavior

    • C.

      Without genes, no behavior could exist and without environment, no gene could be expressed

    • D.

      None of these statements are true

    Correct Answer
    C. Without genes, no behavior could exist and without environment, no gene could be expressed
    Explanation
    This statement explains the interplay between genes and the environment in shaping behavior. It suggests that genes are necessary for behavior to exist, but they need an environment to be expressed. This implies that both genetic factors and environmental factors contribute to the development of behavior.

    Approximately _____ percent of twins are dizygotic

    • A.

      22

    • B.

      66

    • C.

      33

    • D.

      88

    Correct Answer
    B. 66
    Explanation
    Approximately 66 percent of twins are dizygotic. This means that 66 percent of twins are fraternal twins, resulting from the fertilization of two separate eggs by two separate sperm. Dizygotic twins can be of the same or different sexes and share, on average, 50 percent of their genetic material. This is in contrast to monozygotic twins, who are identical twins that result from the fertilization of a single egg that splits into two embryos.

    If one monozygotic twin is nearsighted, the other twin

    • A.

      Will also be nearsighted

    • B.

      Will not be nearsighted

    • C.

      Will have a 90% chance of being nearsighted

    • D.

      Will have a 90% chance of not being nearsighted

    Correct Answer
    C. Will have a 90% chance of being nearsighted
    Explanation
    Monozygotic twins, also known as identical twins, originate from a single fertilized egg and therefore share the same genetic makeup. Nearsightedness, or myopia, has been found to have a genetic component. Studies have shown that if one monozygotic twin is nearsighted, the other twin is likely to also be nearsighted. However, the exact probability may vary. The given answer suggests that there is a 90% chance of the other twin being nearsighted, indicating a high likelihood of the trait being inherited.

    The variable that most often correlates with chromosomal abnormalities is:

    • A.

      The age of the mother

    • B.

      A pregnant mother's drug use

    • C.

      Parent exposure to radiation

    • D.

      The age of the father

    Correct Answer
    A. The age of the mother
    Explanation
    The age of the mother is the variable that most often correlates with chromosomal abnormalities. As women age, the risk of chromosomal abnormalities in their offspring increases. This is because the eggs a woman is born with age over time, and older eggs are more likely to have abnormalities in the chromosomes. On the other hand, the age of the father does not have as significant an impact on the risk of chromosomal abnormalities.

    Down syndrome is a condition in which an individual has 3 copies of:

    • A.

      Chromosome 23

    • B.

      Chromosome 21

    • C.

      Chromosome 26

    • D.

      Chromosome 46

    Correct Answer
    B. Chromosome 21
    Explanation
    Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21. Individuals with Down syndrome have a total of 47 chromosomes instead of the usual 46. This extra chromosome affects the development and functioning of the body and brain, leading to characteristic physical features and intellectual disabilities.

    Which statement is true?

    • A.

      Men are the only carriers for genetic abnormalities

    • B.

      Women over the age of 35 produce abnormal ovum and are at risk of having unhealthy babies

    • C.

      Everyone is a carrier for genetic abnormalities, but usually these conditions are recessive

    • D.

      None of the statements are true

    Correct Answer
    C. Everyone is a carrier for genetic abnormalities, but usually these conditions are recessive
    Explanation
    This statement is true because everyone carries some genetic abnormalities, but most of these conditions are recessive, meaning that they are not expressed unless both parents pass on the abnormal gene. This is why genetic disorders are often seen in families with a history of the disorder. Additionally, it is not accurate to say that only men are carriers for genetic abnormalities or that women over the age of 35 produce abnormal ovum and are at risk of having unhealthy babies.

    An embryo cannot develop without

    • A.

      An X chromosome

    • B.

      A Y chromosome

    • C.

      26 chromosomes

    • D.

      46 chromosomes

    • E.

      3 sex chromosomes

    Correct Answer
    A. An X chromosome
    Explanation
    An embryo cannot develop without an X chromosome because it is a crucial component for determining the sex of the individual. The presence of an X chromosome is necessary for the development of female characteristics, while the presence of a Y chromosome is necessary for the development of male characteristics. Without an X chromosome, the embryo would not have the necessary genetic information to develop into a viable individual.

    Who is more likely to be a carrier of an X-linked trait?

    • A.

      A woman

    • B.

      A man

    • C.

      A colorblind man

    • D.

      A dizygotic twin

    Correct Answer
    A. A woman
    Explanation
    A woman is more likely to be a carrier of an X-linked trait because she has two X chromosomes. If she carries a recessive allele for the trait on one of her X chromosomes, she can still exhibit the dominant allele and not show any symptoms. However, she can pass on the recessive allele to her offspring, making them carriers or showing the trait if they inherit another recessive allele from the father. Men, on the other hand, only have one X chromosome, so if they carry the recessive allele, they will exhibit the trait. A colorblind man is an example of a man exhibiting an X-linked trait. A dizygotic twin does not have any relevance to being a carrier of an X-linked trait.

    In general, genetic counseling is recommended for:

    • A.

      Individuals with achondroplastic dwarfism

    • B.

      Couples who want to know the sex of their fetus

    • C.

      Couples who want to produce twins

    • D.

      Women older than 34 and men older than 39

    Correct Answer
    D. Women older than 34 and men older than 39
    Explanation
    Genetic counseling is recommended for women older than 34 and men older than 39 because advanced parental age increases the risk of genetic disorders in their offspring. As individuals age, the chances of genetic mutations and chromosomal abnormalities occurring in their reproductive cells also increase. Genetic counseling can help these individuals understand the potential risks and make informed decisions about family planning, including the option of undergoing genetic testing to assess the risk of passing on genetic conditions to their children.
