Question

question
birth weight in human babies is an example of what type of selection?
select an answer
a. directional selection
b. stabilizing selection
c. disruptive selection
d. sexual selection

Explanation:

Stabilizing selection favors intermediate phenotypes (e.g., average birth weight in humans, as both very low and very high weights have higher mortality). Directional selection shifts toward one extreme, disruptive toward two extremes, and sexual selection relates to mating. So birth weight in humans is stabilizing selection.

Answer:

B. stabilizing selection
