In a population of $1000$ individuals, $360$ belong to genotype $AA$, $480$ to $Aa$, and the remaining $160$ to $aa$. Based on this data, the frequency of allele $A$ in the population is:

Which of the following factor$(s)$ affect the $Hardy-Weinberg$ equilibrium?

In a population that is not evolving, which of the following can cause a change in allele frequencies in a specific direction?

Lesch-Nyhan disease is an $X$-linked recessive disorder that causes neurological damage in human beings. $A$ survey of $500$ males from a Caucasian population revealed that $20$ were affected with this disorder. What is the frequency of the normal allele in this population?

Genetic equilibrium means

In a population,the frequency of the $M$ allele is $0.8$. Calculate the frequency of the homozygous recessive genotype in that population. (in $\%$)
