Question

Four of the following maintain genetic equilibrium and allele frequencies. Which one is the exception?
A) ​lack of gene flow
B) ​large population interbreeding freely
C) ​differential survival and reproduction
D) ​random mating
E) ​absence of mutations

Quizplus · Accepted Answer

Differential survival and reproduction is the exception because it results in natural selection, which can cause changes in allele frequencies and disrupt genetic equilibrium. The other options (lack of gene flow, large population interbreeding freely, random mating, absence of mutations) do not introduce new alleles or change allele frequencies, thereby maintaining genetic equilibrium.
