Question

2. The influence of genetic drift on allele frequencies increases as:

a. gene flow increases.

b. population size decreases.

c. mutation rate decreases.

d. the number of heterozygous loci increases.

e. all of the above.

Answer 1

B is the answer.

The genetic drift is defined as the random fixation of allele in a population. It is found more predominantly in the small population size as compared to the large population size. Because of sampling error. It leads to decreases the geentic variations in the population. The number of heterozygous loci decreases. The homozygous individual increased by the genetic drift.

The gene flow is not determined by genetic drift. It is determined by the migration.
