Chapters 1–21
CHAPTER 1: INTRODUCTION TO GENETICS
Multiple Choice Questions
1. Genetics is defined as the branch of biology concerned with:
A) The study of cell structure
B) Heredity and variation in organisms
C) The classification of species
D) Ecological interactions between organisms
E) The study of evolution exclusively
Answer: B
Genetics encompasses the study of how traits are transmitted from parents to offspring and the
variation that exists among organisms.
2. Which of the following best describes the central dogma of molecular biology?
A) Protein → RNA → DNA
B) DNA → Protein → RNA
C) DNA → RNA → Protein
D) RNA → DNA → Protein
E) Protein → DNA → RNA
Answer: C
The central dogma describes the flow of genetic information from DNA to RNA (transcription) to protein
(translation).
3. Which scientist is credited with discovering the basic laws of heredity through experiments with pea
plants?
A) Charles Darwin
, B) James Watson
C) Gregor Mendel
D) Thomas Hunt Morgan
E) Francis Crick
Answer: C
Gregor Mendel performed his famous hybridization experiments with Pisum sativum (garden peas) in the
1860s and formulated the basic laws of inheritance.
4. The term "genome" refers to:
A) A single gene on a chromosome
B) The complete set of genetic information in an organism
C) Only the protein-coding regions of DNA
D) The total number of chromosomes in a cell
E) A segment of RNA
Answer: B
The genome is the complete set of DNA (or RNA in some viruses) carried by an organism, including all
genes and non-coding sequences.
5. The rediscovery of Mendel's work around 1900 is attributed to:
A) Watson, Crick, and Wilkins
B) Correns, de Vries, and von Tschermak
C) Morgan, Sturtevant, and Bridges
D) Avery, MacLeod, and McCarty
E) Beadle and Tatum
Answer: B
In 1900, Carl Correns, Hugo de Vries, and Erich von Tschermak independently rediscovered Mendel's
principles of heredity.
6. Which of the following is a model organism widely used in genetic research?
A) Homo sapiens exclusively
B) Drosophila melanogaster
C) Canis lupus familiaris
D) Felis catus
E) Bos taurus
Answer: B
Drosophila melanogaster (fruit fly) is one of the most extensively studied model organisms in genetics
due to its short generation time, large number of offspring, and well-characterized genome.
