Heterozygote advantage should be most closely linked to which of the following?
a) sexual selectionb) stabilizing selectionc) random selectiond) directional selectione) disruptive selection

The correct answer is: B) stabilizing selection

Stabilizing selection is a type of natural selection in which the population mean (non-extreme trait value) is favored over extreme values. It favors the intermediate variants such as heterozygous phenotype (more than both homozygous). This is the most common type of selection, because most traits change little over time (not by favoring extreme traits).
