Hardy-Weinberg equilibrium is not affected by which of the following factors?

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

$A$ gene locus has two alleles $A$ and $a$. If the frequency of the dominant allele $A$ is $0.4$,then what will be the frequency of homozygous dominant,heterozygous,and homozygous recessive individuals in the population?

Which of the following factors can cause a change in the frequency of genes or alleles in future generations?

In which of the following conditions does the gene frequency remain constant in a population?

There are two alleles ($A_1$ and $A_2$) in a population. If the frequency of one allele $(A_1)$ is $0$,then the frequency of the other allele $(A_2)$ is .....
