Ede4ka [16]

Complete question:

Thinking creatively about evolutionary mechanisms, identify at least

two schemes that could generate allelic polymorphism in a population except natural selection that favors heterozygotes.

Select the two correct answers.

-inbreeding among individuals in the population

-purifying selection against mutational variants of alleles in the population

-continuous migration of individuals with new alleles into the population

-mutations that do not severely affect viability and reproductivity

-genetic drift of alleles common in the population

-events leading to genetic bottleneck effect

Answer:

The two events that might favor heterozygotes among the options are

The Continuous migration of individuals with new alleles into the population

Mutations that do not severely affect viability and reproductivity. These might favor heterozygous frequencies.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.
