Question

What conditions must be true for a population to remain in genetic equilibrium?a)gene flow, genetic drift, sexual selection, population isolation, and no mutations
b)gene flow, random mating, no mutations, no genetic variation, and no natural selection
c)large population, sexual selection, gene flow, no mutations, and no natural selection
d)large population, random mating, no migration in or out, no mutations, and no genetic variation

Answer 1

C) Things need to keep moving about and sexual selection allows for preference towards a particular "look". Just going with instinct

Answer 2

Answer: The correct answer is- d) large population, random mating, no migration in or out, no mutations, and no genetic variation.

A population must satisfy five conditions in order to remain in genetic equilibrium. These conditions are as follows-

1) There must be random mating in the population

2) Size of population should be large,

3) There should of migration of organisms in or out of the population,

4) There should be no mutations ( that is change in the genetic material).

5) There should be no natural selection because through natural selection genes that are beneficial are selected and other genes are eliminated from the population.

Thus, option D) is the right answer.
