Detailed explanation-1: -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-2: -When individuals with intermediate phenotypes are favoured and extreme phenotypes are selected against, the selection is said to be stabilizing.

Detailed explanation-3: -A gene pool refers to the combination of all the genes (including alleles) present in a reproducing population or species.

Detailed explanation-4: -What must be true for a population to be in Hardy-Weinberg equilibrium? There must be random mating in the population; there must be an infinite population size; and there must be no evolution occurring (no natural selection, no genetic drift, no migration and no mutation).
