The frequency of the white fur trait in the rabbit population is 50%.
Kamar wants to know his mother's blood type. Kamar
knows that his blood type is AB and his father’s blood
type is heterozygous A. What can Kamar assume about
his mother’s blood type? (1 point)
Kamar’s mother must be either A or O
because blood type AB is considered
incomplete dominant.
Kamar’s mother must be AB because
blood type AB is inherited from one parent
Kamar’s mother must be O because the
recessive allele allows for Kamar to get
type A from his father
Kamar’s mother must be either AB or B
because blood types AB is considered
codominan

Kamar can assume that his mother's blood type must be either AB or B, because blood types AB are considered codominant.
Which of the following best describes natural selection?
(1 point)
The process by which organisms that are
better adapted to the environment tend to
survive and produce more offspring.
The process by which organisms are
separated by chance events, such as
natural disasters, causing the frequency of
the population to change.
When a small sample of a population
leaves and establishes a new population.
When traits are determined by multiple
genes and environmental factors and
cannot be predicted using Punnett squares

What is one similarity between genetic drift and gene
flow? (1 point)
They are both caused by natural disasters,
such as hurricanes.
They both occur in a population by
chance.
They both cause a change in the
frequency of traits in a population.
They are both caused by the migration of
species.
