1. The diagram shows a plant cell. The part of the cell that stores genetic
information is —
A. V
B. X
C. Y
D. Z
2. One type of genetic material that carries the inherited traits of an
organism from parent to offspring is —
A. the nervous system
B. body cells
C. DNA
D. skin
Unit Test: Genetics
3. Why are the offspring produced by sexual reproduction more diverse than
the offspring produced by asexual reproduction?
A. The offspring in sexual reproduction inherit genetic material from two
parents as opposed to one parent.
B. Only sexual reproduction involves cell division.
C. Sexual reproduction passes the genetic information to offspring so that it
remains unchanged.
D. The offspring in sexual reproduction inherit their genetic information
from either their male or female parent.
4. Which of the following best describes the purpose of chromosomes?
A. To release energy by breaking down food molecules
B. To store genetic instructions needed to specify traits
C. To store materials inside the cell
D. To control what enters and exits the cell
5. Which statement best defines genes?
A. A pair of chromosomes in the nucleus
B. A section of DNA stored within a chromosome
C. The expressed trait of an organism
D. The masked allele of an organism

6. The flatworm in the illustration was accidentally cut into three pieces
while swimming among rocks. Each piece will produce a complete worm.
As a result, one flatworm will have produced three offspring. What
conclusion can you make from these observations?
The flatworm produces —
A. offspring identical to one another but different from the parent
B. offspring that are identical to each other and the parent
C. three diverse offspring
D. offspring that will not able to reproduce
7. How does sexual reproduction assist adaptation to changing
environments?
A. Offspring of sexual reproduction have the same genes as each other
and their parent.
B. The combination of traits from two parents creates uniform offspring.
C. Sexual reproduction can be used for regeneration in some organisms.
D. The combination of traits from two parents provides opportunity for
adaptation.
8. The inherited traits of an individual are contained in its —
A. genetic material
B. environment
C. learned behaviors
D. food

9. Two different species of fish are represented below.
Which species of molly reproduces asexually?
A. Sailfin mollies reproduce asexually because one parent contributes all
of the genetic material resulting in uniform offspring.
B. Sailfin mollies reproduce asexually because two parents contribute
their genetic material resulting in diverse offspring.
C. Amazon mollies reproduce asexually because one parent contributes
all of the genetic material resulting in uniform offspring.
D. Amazon mollies reproduce asexually because two parents contribute
their genetic material resulting in diverse offspring.

10. In offspring, when a dominant allele (F) and a recessive allele (f) are
present, which of the following statements is true?
A. The recessive form of the trait will be observed.
B. The recessive allele will blend with the dominant allele.
C. The recessive form will not be observed but will still be present
in the genes.
D. The recessive form will not be observed and cannot be passed
on to future offspring.
11. When two parents produce an offspring, which of the following
statements is true?
A. Each parent randomly passes on copies of half of their
chromosomes.
B. Both parents pass on copies of all of their chromosomes.
C. Each parents get to choose which ones and how many
chromosomes get passed on.
D. Parents don’t pass on any chromosomes.
Unit Test: Genetics
12. The structure shown in the picture provided is found in the nucleus
of the cell and contains genetic material.

reproduction?
