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
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
Rationale: Cystic fibrosis is an autosomal recessive disorder
resulting from mutations in the CFTR gene, illustrating
Mendelian inheritance patterns. Recognizing such disorders
allows nurses to provide better care and management
strategies for affected individuals.
8. In Mendelian inheritance, what is the expected
phenotypic ratio of a monohybrid cross?
A) 1:1
B) 3:1
C) 9:3:3:1
D) 1:2:1
Correct Answer: B) 3:1
Rationale: A monohybrid cross typically results in a 3:1 ratio
