Question

Which one of the following conditions would prevent a population from achieving Hardy-Weinberg equilibrium?

a) No migration occurs between different populations

b) No natural selection occurs

c) Random sampling error does not affect allele frequencies

d) Members of the population mate with each other without regard to phenotypes and genotypes

e) All of the above would prevent a population from achieving Hardy-Weinberg equilibrium.

I already know that option b, c, and d are not the correct answers.

a) No migration occurs between different populations

b) No natural selection occurs

c) Random sampling error does not affect allele frequencies

d) Members of the population mate with each other without regard to phenotypes and genotypes

e) All of the above would prevent a population from achieving Hardy-Weinberg equilibrium.

Ans: A , No migration occurs between different populations.

The Hardy-Weinberg equilibrium can be disturbed by a number of forces:

1) mutations

2) natural selection

3) nonrandom mating

4) genetic drift

5) gene flow.
