Detailed explanation-1: -In a population, the frequency of alleles can be indicated by p2 + q2 + 2pq = 1, where p2 is the frequency of homozygous dominant genotype, q2 is the frequency of recessive genotype and 2pq is the frequency of heterozygous genotype.

Detailed explanation-2: -In order to express Hardy Weinberg principle mathematically, suppose “p” represents the frequency of the dominant allele in gene pool and “q” represents the frequency of recessive allele. p+q=1 since the sum of both frequencies is 100% .

Detailed explanation-3: -The Hardy-Weinberg equation is p2+2pq+q2=1 and is used to determine the frequency of genotypes in a given population. To solve for the frequency of a specific genotype, start by replacing the appropriate terms with the known values you’ve been given.

Detailed explanation-4: -Hardy-Weinberg Equilibrium (HWE) is used to estimate the number of homozygous and heterozygous variant carriers based on its allele frequency in populations that are not evolving.

Detailed explanation-5: -Because there are only two possible alleles, we can say that the frequency of p and q together represent 100% of the alleles in the population (p+q=1).
