    What is mitosis?

    • Process of reductional division in which the number of chromosomes per cell is cut in half.

    • The process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets

    • Your physical appearance

    • Ribbity's eyes

    Correct Answer
    A. The process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets
    Explanation
    Mitosis is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets. This is a crucial process for cell division and growth, as it ensures that each new cell receives a complete set of chromosomes. During mitosis, the chromosomes condense and align in the middle of the cell, then separate and move to opposite ends. Finally, the cell membrane pinches inward, dividing the cytoplasm and creating two new daughter cells, each with the same genetic information as the parent cell.

    Heterozygous means _________________

    Correct Answer
    same, different
    Explanation
    Heterozygous refers to an individual who has two different alleles for a particular gene. This means that the person inherits one allele from each parent, resulting in a genotype that is a combination of two different versions of the gene. Heterozygosity is commonly observed in genetic traits where one allele is dominant and the other is recessive. In such cases, the dominant allele is expressed in the phenotype, while the recessive allele remains hidden. Therefore, heterozygous individuals can have both similar and dissimilar alleles for a specific gene.

    What did Mendel use when he started studying genetics?

    • Oranges

    • Humans

    • Rats

    • Pea plants

    Correct Answer
    A. Pea plants
    Explanation
    Mendel used pea plants when he started studying genetics because they have several advantages for genetic research. Pea plants are easy to grow and have a short life cycle, allowing for quick observations and experiments. They also have distinct traits that can be easily observed and controlled, such as flower color and seed shape. By cross-breeding different pea plants and analyzing the inheritance patterns of these traits, Mendel was able to establish the fundamental principles of genetics.

    Dominant alleles cancel out ________ alleles.

    Correct Answer
    trait, recessive
    Explanation
    Dominant alleles cancel out recessive alleles. In genetics, dominant alleles are expressed and override the effects of recessive alleles. This means that if an individual has a dominant allele for a particular trait, it will be expressed regardless of whether they also have a recessive allele for that trait. The presence of a dominant allele masks the expression of the recessive allele, resulting in the dominant trait being observed.

  • 12. 

    What is the process in which traits are passed on from parents to offspring?

    • Trait

    • Hybrid

    • Mieosis

    • Heredity

    Correct Answer
    A. Heredity
    Explanation
    Heredity is the process in which traits are passed on from parents to offspring. It involves the transmission of genetic information from one generation to the next. This occurs through the inheritance of genes, which are segments of DNA that carry specific instructions for the development and functioning of an organism. Heredity is responsible for the similarities and differences observed between individuals within a species and is a fundamental concept in the field of genetics.

    The shape of DNA is a ___________

    Correct Answer
    Double Helix, Triple Helix
    Explanation
    The shape of DNA is a double helix. This structure consists of two strands that are twisted around each other in a spiral shape, resembling a twisted ladder. Each strand is made up of a sugar-phosphate backbone with nucleotide bases (adenine, thymine, cytosine, and guanine) forming the rungs of the ladder. The double helix structure allows for the replication and transmission of genetic information. Although DNA can form other structures such as triple helix under certain conditions, the most stable and commonly observed form is the double helix.

  • 14. 

    Homozygous means ___________

    Correct Answer
    same, different
    Explanation
    Homozygous refers to the condition where an individual has two identical alleles for a particular gene. This means that both copies of the gene are the same, whether they are dominant or recessive. In contrast, heterozygous refers to having two different alleles for the same gene. Therefore, the correct answer "same, different" accurately represents the concept of homozygous.

  • 15. 

    Hybrid means the same as __________________

    Correct Answer
    homozygous, heterozygous
    Explanation
    The term "hybrid" is used to describe organisms that have two different alleles for a particular trait, one from each parent. This is the same as being "homozygous" or "heterozygous," which also refer to having two different alleles for a specific trait. In all three cases, there is genetic diversity within the organism, resulting in a combination of traits inherited from both parents.

    Rate this question:

  • 16. 

    A _________ is your physical appearance.

    Correct Answer
    phynotype, genotype
    Explanation
    A phenotype is your physical appearance, which is determined by your genotype. The genotype refers to the genetic makeup or the set of genes that an individual possesses. These genes are responsible for various traits and characteristics, such as eye color, hair type, and height. The phenotype is the observable manifestation of these genes, including the physical features that can be seen and measured. Therefore, the correct answer is "phynotype, genotype."

    Cells are the ________ for all living things.

    Correct Answer
    building blocks, germs
    Explanation
    Cells are the building blocks for all living things. They are the fundamental units of life and are responsible for carrying out all the necessary functions and processes that are essential for the survival and functioning of organisms. Cells are responsible for growth, reproduction, metabolism, and maintaining homeostasis. They are the basic structural and functional units that make up all living organisms, ranging from simple single-celled organisms to complex multicellular organisms. Germs, on the other hand, are microorganisms that can cause disease and are not synonymous with cells.

  • 18. 

    DNA is the chemical ___________ for all living things.

    Correct Answer
    makeup, solution
    Explanation
    DNA is the chemical makeup for all living things. It is responsible for carrying the genetic information that determines the traits and characteristics of an organism. DNA is composed of nucleotides that form a double helix structure, and it contains the instructions for building and maintaining an organism. Additionally, DNA acts as a solution by providing the necessary information for cellular processes and functioning. Therefore, the correct answer is "makeup, solution".

    Rate this question:

  • 19. 

    Recessive is alwys represented by the __________

    Correct Answer
    Big letter, Little letter
    Explanation
    In genetics, the terms "big letter" and "little letter" are commonly used to represent dominant and recessive alleles, respectively. Dominant alleles are usually represented by capital letters, while recessive alleles are represented by lowercase letters. This allows scientists to easily distinguish between the two types of alleles when studying inheritance patterns. Therefore, the correct answer is "Big letter, Little letter."
