Which one of the following factors will not affect the Hardy-Weinberg equilibrium?

$A$ population is in Hardy-Weinberg equilibrium for a gene with only two alleles. If the gene frequency of an allele $A$ is $0.7$,the genotype frequency of $Aa$ is

According to the Hardy-Weinberg principle,allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. It makes several assumptions which are given below:
$i.$ Random Mating
$ii.$ Sexual Reproduction
$iii.$ Non-overlapping Generations
$iv.$ Occurrence of Natural Selection
$v.$ Small size of population
Identify two assumptions which do not meet the criteria for a population to reach Hardy-Weinberg Equilibrium.

Select the correct statement.

Which one of the following factors does not allow the $Hardy-Weinberg$ principle to operate?

In the presence of mutation,migration,and selection,if gene frequencies change in a population,this change is due to:
