Test Bank for Essentials of Genetics, 10th Edition –
Klug, Cummings, Spencer, Palladino & Killian
Note: The 10th Edition of Essentials of Genetics by Klug, Cummings, Spencer, Palladino
& Killian contains 21 chapters plus 7 Special Topics chapters . The textbook covers
foundational genetics topics from Mendelian inheritance through population genetics,
with special topics on epigenetics, genetic testing, gene therapy, neurogenetics, DNA
forensics, genetically modified foods, and genomics/precision medicine .
Instructions: Each question has one best answer. Correct answers are bolded, followed
by a rationale and chapter reference.
Chapter 1: Introduction to Genetics
,1. 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.
A) Identifying genes
B) Editing genes
C) Producing new genes
D) Regulating genes
E) Transmitting genes
Rationale: The CRISPR-Cas system is a revolutionary genome-editing tool that allows
scientists to precisely edit genes. It has enormous potential for correcting genetic
mutations associated with human disorders .
2. In the 1600s, William Harvey studied reproduction and development. What is
the term given to his theory which states that an organism develops from the
fertilized egg by a succession of developmental events that lead to an adult?
A) Preformation
B) Spontaneous generation
C) Cell theory
D) Transduction
E) Epigenesis
Rationale: Epigenesis is the theory that an organism develops from the fertilized egg by
a succession of developmental events that lead to an adult .
3. Transmission genetics is the study of:
A) The structure and function of chromosomes
B) The chemical nature of the gene
C) How traits are passed from parent to offspring
D) The evolutionary relationships between species
E) How genes are regulated
Rationale: Transmission genetics (Mendelian genetics) focuses on how traits are
inherited and passed from one generation to the next .
4. August Weismann's germ-plasm theory stated that:
A) Acquired characteristics can be inherited
B) Only the germ cells (sperm and egg) carry hereditary information
C) Somatic cells can pass traits to offspring
,D) All cells contain the same hereditary material
E) Traits are blended in offspring
Rationale: Weismann's germ-plasm theory proposed that hereditary information is
carried only in the germ cells (sperm and egg), not in somatic cells. This disproved
Lamarckian inheritance of acquired characteristics .
5. The basic unit of heredity is the:
A) Chromosome
B) Nucleotide
C) Gene
D) Protein
E) Allele
Rationale: A gene is the fundamental physical and functional unit of heredity, carrying
the information for a specific trait .
6. Which of the following best describes a genome?
A) A single gene
B) All the DNA found within a cell
C) A single chromosome
D) A protein molecule
E) A set of alleles
Rationale: A genome is the complete set of genetic information (DNA) contained within
a cell or organism .
7. Who is credited with the rediscovery of Mendel's work in 1900?
A) Darwin and Wallace
B) Watson and Crick
C) de Vries, Correns, and von Tschermak
D) Morgan and Sturtevant
E) Beadle and Tatum
Rationale: Hugo de Vries, Carl Correns, and Erich von Tschermak independently
rediscovered Mendel's principles of inheritance in 1900 .
8. Who developed the technique of X-ray diffraction to study DNA structure?
, A) Watson and Crick
B) Franklin and Wilkins
C) Mendel and Darwin
D) Morgan and Bridges
E) McClintock and Creighton
Rationale: Rosalind Franklin and Maurice Wilkins used X-ray diffraction to produce
images of DNA, which were critical for Watson and Crick's determination of the double
helix structure .
9. The Human Genome Project was completed in:
A) 1990
B) 1995
C) 2001
D) 2003
E) 2010
Rationale: The Human Genome Project was completed in 2003, providing the complete
sequence of the human genome .
10. The "one gene-one enzyme" hypothesis was proposed by:
A) Mendel
B) Morgan
C) Beadle and Tatum
D) Watson and Crick
E) McClintock
Rationale: Beadle and Tatum proposed the "one gene-one enzyme" hypothesis based
on their studies of Neurospora crassa (bread mold). It has since been modified to "one
gene-one polypeptide" .
11. Offspring that result from crosses between true-breeding parents with
different traits:
A) Are true-breeding
B) Make up the F2 generation
C) Make up the parental generation
D) Are called hybrids
Rationale: Hybrids are offspring resulting from crosses between true-breeding parents
with different traits .
