Answer: D) Non random mating
In 1908, Hardy-Weinberg proposed that frequency of allele and genotype in a population remain constant from one generation to another only if population is stable and is in genetic equilibrium.
He gave five condition in order to keep the population in Hardy-Weinberg equilibrium. These are:
a) A large breeding population
b) Random mating
c) No change in allelic frequency due to mutation
d) No immigration or emigration
e) No natural selection
