Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What does being in Hardy-Weinberg equilibrium mean for a population?
A
The population is evolving
B
The population is not evolving
C
Equilibrium would gradually end
D
Gene flow would occur but slowly
Explanation: 

Detailed explanation-1: -When a population is in Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies will stay the same across generations. There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.

Detailed explanation-2: -The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

Detailed explanation-3: -The Hardy-Weinberg equilibrium principle describes the unchanging frequency of alleles and genotypes in a stable, idealized population. In this population we assume there is random mating and sexual reproduction without normal evolutionary forces such as mutation, natural selection, or genetic drift.

Detailed explanation-4: -The Hardy-Weinberg Equilibrium (HWE) is an important fundamental principal of population genetics, which states that “genotype frequencies in a population remain constant between generations in the absence of disturbance by outside factors” (Edwards, 2008).
