Question

If a population experiences no migration, is very large, has no mutations, has random mating, and there is no selection, which of the following would you predict?

A .The makeup of the population’s gene pool will remain virtually the same as long as these conditions hold

b. The population will evolve, but much more slowly than normal

c. Dominant alleles in the population’s gene pool will slowly increase in frequency while recessive alleles will decrease

d. The composition of the population’s gene pool will change slowly in a predictable manner

e. The population probably has an equal frequency of A and a alleles

Explanation / Answer

Ans: A .The makeup of the population’s gene pool will remain virtually the same as long as these conditions hold

Explanantion:

The conditions described all contribute to genetic equilibrium, where it would be expected for initial gene frequencies to remain constant generation after generation. If we chose option e, the genetic equilibrium does not mean that the frequency of A is equal to the frequency of a.
