What happens when a population is in hardy-weinberg equilibrium?
a. mutations are common
b. organisms produced of organisms produced no offspring
c. allele frequency is stable
d. there are infinitely alleles

C; Allele Frequency is stable.

Explanation:

When a population is in Hardy-Weinberg equilibrium, there are five conditions within that: 1) no mutations, 2) random mating among organisms, 3) no gene flow (meaning no exchange of alleles among different populations through either immigration or emigration), 4) large population size and 5) no natural selection. If there can be no mutations in the alleles, no gene flow and no natural selection, then the allele frequencies of a population in Hardy-Weinberg equilibrium must be stable with no fluctuations.

C. Allele is stable
