What is Balanced Polymorphism in a Population Likely the Result

Question

What is balanced polymorphism in a population likely the result of?
A) disruptive selection
B) sexual selection
C) directional selection
D) stabilizing selection

Accepted Answer

Balanced polymorphism is a situation in a population where two or more distinct traits in a population are maintained through natural selection. Disruptive selection, which favors individuals at both extremes of a trait over those with intermediate traits, is a mechanism that can lead to balanced polymorphism by supporting the survival and reproduction of individuals with distinct or extreme phenotypes, rather than those with average phenotypes.
