Chapter 1: Introduction to Genetics (Questions 1–28)
1. Which of the following sequences correctly shows the flow of genetic information during
gene expression?
A. RNA → DNA → Protein
,B. DNA → RNA → Protein
C. Protein → RNA → DNA
D. DNA → Protein → RNA
Answer: B. DNA → RNA → Protein
Rationale: The central dogma of molecular biology describes the flow of genetic
information from DNA to RNA (transcription) to protein (translation).
2. The three major divisions of genetics are:
A. Transmission genetics, molecular genetics, and population genetics
B. Mendelian genetics, chromosomal genetics, and evolutionary genetics
C. Classical genetics, modern genetics, and genomic genetics
D. Cellular genetics, organismal genetics, and ecological genetics
Answer: A. Transmission genetics, molecular genetics, and population genetics
Rationale: Pierce identifies three major subdivisions: transmission genetics (heredity
principles), molecular genetics (gene structure and function), and population genetics
(genetic composition of groups).
3. Albinism is rare in most human populations (about 1 in 20,000) but occurs at a frequency
of 1 in 200 in certain Hopi villages. This is best explained by:
A. A higher mutation rate among the Hopi
B. Natural selection favoring albinism in Hopi culture
C. Genetic drift due to a small population
D. Gene flow from neighboring populations
Answer: B. Natural selection favoring albinism in Hopi culture
Rationale: Among the Hopi, albinos are viewed positively, often occupy leadership
positions, and may have increased mating opportunities, allowing alleles for albinism to
persist at higher frequencies.
, 4. Which of the following is a model genetic organism?
A. Homo sapiens
B. Caenorhabditis elegans
C. Pantroglodytes (chimpanzee)
D. Linaria vulgaris
Answer: B. Caenorhabditis elegans
Rationale: C. elegans (a nematode worm) is a classic model genetic organism due to its
short life cycle, small genome, and ease of laboratory culture.
5. Which of the following would serve the LEAST well as a model for understanding basic
mechanisms of inheritance?
A. Fruit flies
B. Humans
C. Yeast
D. Mice
Answer: B. Humans
Rationale: Humans are poor model organisms for basic inheritance studies due to long
generation times, small family sizes, and ethical constraints.
6. Identify a TRUE statement concerning genetics.
A. The theory of pangenesis states that all living organisms are composed of cells.
B. Bacteria and viruses are not useful in studying genes and inheritance.
C. Charles Darwin accurately described the laws of inheritance.
D. Many human traits, such as skin and hair color, are determined by more than a single
gene.
Answer: D. Many human traits, such as skin and hair color, are determined by more than a
single gene.
