Chapter 1: Introduction to Genetics from Genetics: A Conceptual Approach
1. Which of the following best defines genetics?

A) The study of living organisms

B) The study of genes and heredity

C) The study of diseases and their causes

D) The study of cell structures

Correct Answer: B) The study of genes and heredity

Rationale: Genetics focuses specifically on how traits and characteristics are inherited through
genes. This foundational knowledge is crucial for understanding more complex genetic concepts.
Understanding genetics is essential for nurses, as they may deal with genetic conditions and
counseling.

2. Which term describes the observable characteristics of an organism?

A) Genotype

B) Phenotype

C) Allele

D) Chromosome

Correct Answer: B) Phenotype

Rationale: The phenotype refers to the physical expression of genetic traits, while genotype refers
to the genetic makeup. Nurses must be able to differentiate between these terms to provide
effective education and support to patients regarding genetic conditions.

3. What is the primary function of DNA?

A) To provide energy for cellular processes

B) To store and transmit genetic information

C) To catalyze biochemical reactions

D) To serve as a structural component of cells

Correct Answer: B) To store and transmit genetic information

Rationale: DNA holds the instructions for the development and functioning of living organisms,
which is central to genetic studies. Understanding the role of DNA is vital for nurses, especially
when discussing genetic testing and counseling.

4. Which of the following best describes alleles?

A) Different forms of a gene

B) The same form of a gene

, TESTBANKS BY NURSINGNERD



C) Chromosomes that determine sex

D) Cells that contain genetic material

Correct Answer: A) Different forms of a gene

Rationale: Alleles represent variations of a particular gene, contributing to genetic diversity. Nurses
must understand alleles to help explain inheritance patterns and genetic disorders to patients.

5. If a person has two identical alleles for a trait, they are considered:

A) Homozygous

B) Heterozygous

C) Dominant

D) Recessive

Correct Answer: A) Homozygous

Rationale: Homozygous individuals have two copies of the same allele, while heterozygous
individuals have different alleles. This distinction is essential in genetics, as it influences the
expression of traits and the risk of genetic disorders.

6. What is a gene?

A) A segment of DNA that codes for a protein

B) The physical location of chromosomes

C) The complete set of DNA in an organism

D) A structure that carries nutrients in cells

Correct Answer: A) A segment of DNA that codes for a protein

Rationale: Genes are the basic units of heredity and are crucial for producing proteins that carry out
various functions in the body. Understanding gene function is essential for nurses to assess genetic
risks and provide appropriate patient education.

7. Which genetic disorder is caused by a single gene mutation?

A) Cystic fibrosis

B) Down syndrome

C) Turner syndrome

D) Hemophilia

Correct Answer: A) Cystic fibrosis
