Question

question 2
what is decreased as a result of stabilizing selection?
a the middle phenotypic range of variation
b one extreme of the phenotypic variation range
c population growth
d the range of phenotypic variation
e the most suited phenotypic range

Explanation:

Stabilizing selection favors intermediate phenotypes. It reduces the range of phenotypic variation by selecting against extreme phenotypes. For example, in human birth weight, very low or very high weights are selected against, and intermediate weights are favored. This leads to a decrease in the range of phenotypic variation.

Answer:

D. the range of phenotypic variation
