Note: The 13th Edition (©2026, published July 2025) of Concepts of Genetics by William
S. Klug, Michael A. Palladino, and Darrell Killian contains 26 chapters organized into 5
parts, plus 6 Special Topics chapters . The test bank covers Chapters 1–26 and Special
Topics 1–6 .
Below is a comprehensive exam with 200 multiple-choice questions with bolded
correct answers and rationales, covering all chapters and special topics.
Part I: Genes, Chromosomes, and Heredity
,Chapter 1: Introduction to Genetics
1. What is the name of the company or institution that has access to the health,
genealogical, and genetic information of approximately 270,000 residents of
Iceland?
A) National Institutes of Health
B) deCODE
C) Gattaca
D) Biogen
Rationale: deCODE genetics is a biotechnology company that created a database
containing health, genealogical, and genetic information of approximately 270,000
residents of Iceland .
2. Why did deCODE select Iceland for its ambitious research project?
A) A relatively low degree of genetic diversity
B) Frequent and extensive mutational bursts
C) High genetic diversity
D) Lack of genealogical information
Rationale: Iceland was selected due to its relatively low degree of genetic diversity and
extensive genealogical records .
3. The genetic material DNA consists of basic subunits called:
A) Mitochondria
B) Lysosomes
C) Centrioles
D) Nucleotides
Rationale: DNA is composed of repeating subunits called nucleotides, each consisting
of a phosphate group, a deoxyribose sugar, and a nitrogenous base .
,4. The immediate product of transcription is:
A) A phospholipid
B) An amino acid
C) A protein
D) RNA
Rationale: Transcription is the process by which DNA is used as a template to
synthesize RNA .
5. In many species, there are two representatives of each chromosome. In such
species, the characteristic number of chromosomes is called the ______ number. It is
usually symbolized as ______.
A) Haploid; n
B) Haploid; 2n
C) Diploid; 2n
D) Diploid; n
Rationale: The diploid number (2n) refers to the characteristic number of chromosomes
where there are two representatives of each chromosome .
6. Genetics is the study of:
A) Heredity and variation
B) Mutation and recession
C) Transcription and translation
D) Diploid and haploid
Rationale: Genetics is defined as the branch of biology associated with heredity and
variation .
7. Early in the twentieth century, Walter Sutton and Theodor Boveri noted that the
behavior of chromosomes during meiosis is identical to the behavior of genes
, during gamete formation. They proposed that genes are carried on chromosomes,
which led to the basis of the:
A) Chromosome Theory of Inheritance
B) Law of Segregation
C) Law of Independent Assortment
D) Germ-plasm theory
Rationale: The Chromosome Theory of Inheritance, proposed by Sutton and Boveri,
states that genes are located on chromosomes .
8. What is a mutation?
A) An inherited change in DNA sequences that is the source of all genetic variation
B) A change in DNA that leads to death
C) An inherited change in DNA sequence that is always bad for an organism
D) A temporary change in DNA
Rationale: A mutation is an inherited change in DNA sequences that serves as the
source of all genetic variation .
9. What is a simple definition of an allele?
A) A variant form of a gene
B) A chromosome
C) A protein
D) A gene
Rationale: An allele is a variant form of a gene .
10. The CRISPR-Cas system potentially represents one of the most powerful
techniques in genetics as a result of its role in ______ associated with specific human
disorders.
