A Population That is in Genetic Equilibrium is Said to ____

Question

A population that is in genetic equilibrium is said to ____.
A) have an equal number of homozygotes as heterozygotes for a given trait
B) deviate from the Hardy-Weinberg law
C) require genetic testing for estimation of allele frequencies
D) lose genetic variation with each generation
E) have an allele or alleles that remain constant generation to generation

Accepted Answer

A population in genetic equilibrium has an allele or alleles that remain constant from generation to generation, which is the definition of genetic equilibrium according to the Hardy-Weinberg law. Option A is not always true in a population in genetic equilibrium, as it depends on the specific allele frequencies. Option B states the opposite of genetic equilibrium, and option C is not necessary to determine genetic equilibrium. Option D is true for populations that undergo genetic drift, but not for those in genetic equilibrium.
