In parts of africa where malaria is prevalent, individuals who are heterozygous for sickle cell disease are at an advantage. this, as well as other examples of heterozygote advantage, should be most closely linked to which of the following? a. sexual selectionb. stabilizing selectionc. disruptive selectiond. directional selection

B. Stabilizing selection

Explanation:

Stabilizing selection is a type of natural selection in which mean value of trait is favourable. It is different than disruptive selection in which extreme values are favoured over intermediate values and different than directional selection in which one extreme phenotype is favored over others.

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
