Which factors can prevent permanent fixation of an allele (i. e. maintain genetic diversity) ? Hint: You're going to have to try different values than just those presented in the exercise--try to keep both alleles present! (A) Genetic Drift (B) Natural Selection (C) Mutation (D) Gene Flow

The answer is Genetic drift and natural selection.

Explanation:

Genetic drift is a change is genetic composition that enhances organisms adaptation to an environment. The continuous change gives an extra advantage and enhances better chances of survival

Natural selection is the process that results in the adaptation of an organism to its environment by relatively reproducing its genes.

This two factors are the major factors that like causes allele fixation
