Explain Hardy-Weinberg equilibrium and why it is so important, especially since all of its assumptions seem so unrealistic and difficult to meet.

The Hardy-Weinberg equilibrium principle states that ideally a population's genetic variation does not change for every generation. That is with random mating within a large population where all influencing factors are constant, it predicts the constant frequencies of genotype and allele because of their equilibrium state

Explanation:

The principle provides a foundation for studying popupulation variation between generations when influencing factors such as genetic mutations, natural selection forces, guided mating, drift in genetics and transfer of genetic variation between populations are considered
