Genetics is
- A.
  
  The study of family trees
- B.
  
  The study of Heredity
- C.
  
  The passing of traits from parent to offspring
- D.
  
  The study of Reproduction
- E.
  
  None of the above
Correct Answer
B. The study of Heredity

Explanation
The correct answer is "The study of Heredity." Genetics is the branch of biology that focuses on the study of heredity, which involves the passing of traits from parents to their offspring. It involves the understanding of how genes are inherited and how they contribute to the development of traits and characteristics in living organisms. By studying genetics, scientists can gain insights into the mechanisms of inheritance and how genetic variations can lead to differences in traits among individuals.

Homozygous- Organisms that inherit two _______ alleles

Correct Answer
Different
Identical

Explanation
Homozygous organisms inherit either two different alleles or two identical alleles for a particular trait. When an organism has two different alleles, it is referred to as heterozygous. On the other hand, when an organism has two identical alleles, it is referred to as homozygous. Therefore, the correct answer is "Different, Identical".

9.

Genotype is ______ characteristics

Correct Answer
genetic
physical

Explanation
Genotype refers to the genetic makeup of an individual, which determines their inherited traits and characteristics. It encompasses the combination of genes present in an organism, influencing not only physical attributes but also various genetic traits. Therefore, the correct answer is genetic and physical, as genotype encompasses both genetic and physical characteristics.

- C.
  
  A pair of genes that determine a particular trait
- D.
  
  DNA stored inside a cell's membrane
- E.
  
  None of the above
Correct Answer
C. A pair of genes that determine a particular trait

Explanation
The correct answer is "A pair of genes that determine a particular trait." Alleles are different forms of a gene that occupy the same position on a chromosome. They can be dominant or recessive and determine the expression of a particular trait in an organism. Each individual inherits one allele from each parent, and the combination of alleles determines the traits that the offspring will have. Therefore, alleles can be considered as a pair of genes that determine a specific trait.

Dominant Alleles
- A.
  
  A pair of genes that determine a particular trait
- B.
  
  In a pair of alleles, the one that, if present, determines that trait
- C.
  
  Is homozygous in nature
- D.
  
  Is heterozygous in nature
- E.
  
  None of the above
Correct Answer
B. In a pair of alleles, the one that, if present, determines that trait

Explanation
Dominant alleles are the alleles that, if present in a pair of genes, will determine a particular trait. This means that even if there is one dominant allele and one recessive allele in the pair, the dominant allele will be expressed and the trait associated with it will be observed. In contrast, recessive alleles will only be expressed if both alleles in the pair are recessive. Therefore, the correct answer is "In a pair of alleles, the one that, if present, determines that trait."

DNA stands for
- A.
  
  Deoxyribonucleic acid
- B.
  
  Reoxyribonucleic acid
- C.
  
  Neoxyribonucleic acid
- D.
  
  Deoxyflibonucleic acid
- E.
  
  None of the above
Correct Answer
A. Deoxyribonucleic acid

Explanation
DNA stands for deoxyribonucleic acid. It is a molecule that contains the genetic instructions for the development and functioning of all living organisms. DNA is composed of two strands twisted together in a double helix structure, and it carries the genetic information in the form of a code made up of four nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G). The correct answer, deoxyribonucleic acid, accurately represents the full name of this important molecule.

Genes
- A.
  
  Create disease in the body
- B.
  
  Are stored in the nucleus of the cell
- C.
  
  Hold the traits passed from your parents
- D.
  
  Are tasty candy treats
- E.
  
  Both A and C
Correct Answer
B. Are stored in the nucleus of the cell

Explanation
Genes are stored in the nucleus of the cell. The nucleus is the control center of the cell, where genetic material is housed. Genes contain the instructions for building and maintaining the body, and they are passed down from parents to their offspring, carrying traits and characteristics. Therefore, genes play a crucial role in determining an individual's physical and biological characteristics.

Dave Watson and Marcus Crick
- A.
  
  Created the gene model
- B.
  
  Created a hereditary model
- C.
  
  Created the DNA model
- D.
  
  Created the punnet square
- E.
  
  None of the above
Correct Answer
C. Created the DNA model

Explanation
Dave Watson and Marcus Crick are credited with creating the DNA model. This model revolutionized our understanding of genetics and provided a visual representation of the structure of DNA, including its double helix shape and the arrangement of its nucleotide base pairs. The DNA model has been instrumental in advancing the field of molecular biology and has had a profound impact on our understanding of heredity and genetic inheritance.

The double Helix is described as
- A.
  
  The twisted genes
- B.
  
  The twisted ladder
- C.
  
  The crooked genes
- D.
  
  The crooked ladder
- E.
  
  All of the above
Correct Answer
B. The twisted ladder

Explanation
The double helix is described as the twisted ladder because its structure resembles a twisted ladder or spiral staircase. The two strands of DNA are coiled around each other in a helical shape, forming a double helix. This twisted ladder structure allows the DNA molecule to be compact and stable while still being able to separate the strands for replication and transcription processes.

The sides of the double helix are made of
- A.
  
  Deoxyribose and glucose
- B.
  
  Phosphate and genes
- C.
  
  Phosphate and heterozygous genes
- D.
  
  Deoxyribose and phosphate
- E.
  
  None of the above
Correct Answer
D. Deoxyribose and phosphate

Explanation
The sides of the double helix are made of deoxyribose and phosphate. Deoxyribose is a sugar molecule that forms the backbone of DNA, while phosphate groups connect the sugar molecules together. This combination of deoxyribose and phosphate forms the alternating sugar-phosphate backbone of the DNA molecule.

______ always pairs with ______

Correct Answer
cytosine/DNA
guanine/cytosine
phosphate/protein

Explanation
The pairing of cytosine with DNA is a fundamental concept in molecular biology. In DNA, cytosine always forms a complementary base pair with guanine. This pairing is crucial for maintaining the double-stranded structure of DNA and for the accurate replication and transmission of genetic information. The other options, guanine/cytosine and phosphate/protein, do not represent the correct pairing in this context.
