Question 1
Contrast directional and stabilizing forms of selection.Question 2
One of the Hardy-Weinberg assumptions states that all genotypes in the population are free of selective advantage. What influence might a selective advantage of a genotype have on a Hardy-Weinberg equilibrium?Answer 1
In directional selection, a particular phenotypic extreme is selected for; in stabilizing selection, both extreme phenotypes are selected against.Answer 2
Certain alleles will reach the next generation on a nonrandom basis, thus upsetting the equilibrium.
