In the Hardy-Weinberg equation $p^{2} + 2pq + q^{2} = 1$,which term represents the frequency of heterozygous individuals?

If the measured allele frequency differs from the expected value,what does it indicate?

$A$ 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

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:

In Gir forest,out of $100$ individuals,$40$ individuals are recessive. Calculate the percentage of heterozygous progeny by the Hardy-Weinberg principle. (in $\%$)

Which of the following is the correct formula for the Hardy-Weinberg principle?
