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
ANS: 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
ANS: 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
ANS: 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
ANS: 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
,TEST BANK FOR GENETICS A CONCEPTUAL APPROACH 7TH EDITION
BY: BENJAMIN A. PIERCE
ANS: 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
ANS: 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
ANS: 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
ANS: B) 3:1
Rationale: A Monohybrid Cross Typically Results In A 3:1 Ratio Of Dominant
To Recessive Phenotypes. This Knowledge Is Important For Nurses Involved
In Genetic Counseling, As It Helps Explain Inheritance Patterns To Families.
9. Which Of The Following Represents A Carrier For A Recessive Genetic Disorder?
A) AA
B) Aa
C) Aa
D) None Of The Above
ANS: B) Aa
Rationale: A Carrier Has One Dominant And One Recessive Allele, Showing
No Symptoms Of The Disorder But Capable Of Passing The Recessive Allele
To Offspring. Understanding Carriers Is Vital In Genetic Counseling And
Assessing Family Risks.
10. What Is The Significance Of The Human Genome Project?
A) To Clone Human Genes
B) To Map The Entire Human Genome
C) To Identify Genetic Disorders Only
