Chapter 1: Overview of Genetics
1. What is the primary molecule responsible for storing
genetic information in most living organisms?
a) Ribonucleic Acid (RNA)
b) Protein
c) Deoxyribonucleic Acid (DNA)
d) Carbohydrate
2. The complete genetic makeup of an organism is referred to
as its:
a) Proteome
b) Chromosome
c) Genome
d) Phenotype
3. The process by which a gene's information is used to create
a functional product, like a protein, is known as:
a) Gene expression
b) DNA replication
c) Genetic recombination
d) Cellular differentiation
,4. Which of the following is a primary goal of transmission
genetics?
a) To study the structure and function of genes at the molecular
level
b) To analyze the genetic composition of populations
c) To understand the relationship between genes and
chromosomes
d) To examine the patterns of inheritance from parents to
offspring
5. A change in the DNA sequence of a gene is called a:
a) Allele
b) Mutation
c) Recombination
d) Translation
Chapter 2: Mendelian Inheritance
6. In a monohybrid cross between two heterozygous (Aa)
individuals, what is the expected phenotypic ratio in the
offspring?
a) 1:1
b) 3:1
c) 1:2:1
d) 9:3:3:1
, 7. An organism with two different alleles for a given gene is
described as:
a) Homozygous
b) Heterozygous
c) Hemizygous
d) Homologous
8. The observable characteristics of an organism are its
______, while its genetic makeup is its ______.
a) Genotype; phenotype
b) Phenotype; genotype
c) Alleles; loci
d) Traits; genes
9. A testcross is used to:
a) Determine if an individual is homozygous dominant or
heterozygous
b) Create a dihybrid cross
c) Calculate mutation rates
d) Sequence a genome
10. Mendel's Law of Segregation states that:
a) Alleles of different genes assort independently of each other
during gamete formation.
b) Chromosomes are sorted into gametes randomly.
c) The two alleles for a gene separate during gamete formation.
