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?
GENETICS A CONCEPTUAL APPROACH 7TH EDITION
,GENETICS A CONCEPTUAL APPROACH 7TH EDITION
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
GENETICS A CONCEPTUAL APPROACH 7TH EDITION
, 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
