Heterozygote Advantage Should Be Most Closely Linked to Which of the Following

Question

Heterozygote advantage should be most closely linked to which of the following?
A)sexual selection
B)stabilizing selection
C)random selection
D)directional selection
E)disruptive selection

Accepted Answer

Heterozygote advantage occurs when individuals who carry two different alleles for a given trait have a greater fitness than individuals who are homozygous for either allele. This results in a selective pressure towards maintaining both alleles in the population, leading to stabilizing selection. Therefore, heterozygote advantage is most closely linked to stabilizing selection.
