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.
