B.
a change in the allelic frequency within a population due to random chance
C.
a change in the allelic frequency within a population due to differential reproductive success.
cess.
D.
the transfer of alleles from one breeding population to another.

Answer 1

B a change in the allelic frequency within a population durd to random change

Answer 2

Answer:a change in the allelic frequency within a population due to random chance.

Explanation:

Genetic drift is a change in the allelic frequency within a population due to random chance. It is especially apparent within small breeding populations.

For example, genetic drift can result in an allele being completely lost from a population by random chance, regardless of whether the allele has any effect on an individual's chance of survival or its reproductive success.
