Which Assumption Pertains to a Population in a Hardy- Weinberg

Question

Which assumption pertains to a population in a Hardy- Weinberg equilibrium?
A)a selectively mating population
B)no migration,mutation or,genetic drift
C)a selective advantage of one genotype
D)a small population

Accepted Answer

A population in a Hardy-Weinberg equilibrium assumes that there is no migration, mutation, or genetic drift occurring in the population. This means that the population is not being influenced by outside factors and is in a state of genetic equilibrium. The other options, such as a selectively mating population or a selective advantage of one genotype, would disrupt the equilibrium and result in changes to the population's gene frequencies. A small population could potentially be in a Hardy-Weinberg equilibrium, but it is not a necessary assumption.
