The observable traits expressed by an organism are
described as its:
Zygote
Alleles
Genotype
Phenotype - ANSWER-Phenotype
Half of the gametes produced by an organism with the
genotype Aa will receive the A allele, while half will receive
the a allele. This is a demonstration of:
independent assortment
mutation
random fertilization
segregation - ANSWER-segregation
Which of the following is true about genes that are located
on different chromosomes?
,2|Page
These genes are inherited independently of each other.
Only the dominant alleles of these genes tend to be
inherited together.
These genes are always inherited together.
These genes are more likely to undergo mutation. -
ANSWER-These genes are inherited independently of
each other.
A recessive trait will be observed in individuals that are
homozygous for that trait. - ANSWER-homozygous
What are the types of gametes that can be produced by
an individual with the genotype AaBb?
Aa, Bb
AA, aa, BB, bb
AB, Ab, aB, ab
AB, ab - ANSWER-AB, Ab, aB, ab

Genetic inheritance is being studied in a certain species of
plant in which orange flower color (O) is dominant to white
(o) and round leaf shape (S) is dominant to oval (s). A
true-breeding orange-flowered, round-leaved male plant
(Plant A) is mated with a true-breeding white-flowered,
oval-leaved female plant (Plant B) to produce dihybrid
offspring plant (Plant C). Assuming normal Mendelian
genetics and independent inheritance of these two traits,
which gametes might be produced by Plant C?
OoSs
OS
oS
Both OS and oS
Both OoSs and OS - ANSWER-Both OS and oS
Daughter cells produced by mitosis:
, 4|Page
are genetically identical to the parent cell
are only created in females
divide the cytoplasm into four parts
cause cancer - ANSWER-are genetically identical to the
parent cell
In a cross between a white-eyed female fruit fly and a red-
eyed male fruit fly, what is the expected outcome?
All male offspring with white eyes
All female offspring with white eyes
All offspring with red eyes
All offspring with white eyes - ANSWER-All male offspring
with white eyes
Hemophilia has an X-linked recessive pattern. It is carried
on the "X" chromosome. It is only expressed
phenotypically as homozygous recessive in women but
men that inherit the affected chromosome will suffer from
the disorder. A carrier woman (one affected X
chromosome) married a man with hemophilia, and they
have children. What percent of their boy children will be
affected with hemophilia?
