An allele, "r", is recessive to "R" such that Rr homozygotes
have wildtype (RR) fitness, but rr homozygotes fail to develop
properly and die a few days after fertilization. If R and r are
initially present at equal frequencies, natural selection:
[Choose all that apply]
Group of answer choices
a. will tend to keep the population in Hardy-Weinberg
Equilibrium
b. will not favor either allele
c. will favor Rr heterozygotes as a form of overdominance
d. will initially act strongly against the r allele
e. will not act strongly against the r allele once it becomes
rare in the population
