mating in this population is random

Explanation:

According to Hardy-Weinberg equilibrium, allele frequencies in a population remain constant for generations in absence of evolutionary forces like genetic drift, natural selection, mutation etc. A population is in Hardy-Weinberg equilibrium if there is random mating (not biased towards a particular phenotype), no gene flow, large population size, no mutation and no selection. These factors are important as disturbing them will change the allele frequency. Hence, if this population is in Hardy-Weinberg equilibrium we can assume that mating in this population is random.
