Question

Which of the mechanisms below increases the amount of genetic variations in a population?

a. Genetic drift
b. Gene flow
c. Bottleneck effect
d. Founder effect

Answer 1

"Gene flow" is the one mechanism among the choices given in the question that increases the amount of genetic variations in a population. The correct option among all the options that are given in the question is the second option or option "B". I hope that the answer has come to your help.

Answer 2

The correct option is B.

Gene flow refers to the movement of genes from one population to another population. The movement of genes in and out of a particular population usually result in significant changes in the gene frequencies of the population members that are carrying specific variant of a particular genes. Thus leading to increase in the amount of genetic variations in that population.
