<h2>Frequency of allele </h2>

Explanation:

Hardy Weinberg Equilibrium is used to calculate the allelic as well as genotypic frequency

Allelic frequency of dominant and recessive allele is represented by p and q respectively whereas genotypic frequency of dominant genotype is represented by p2 and q2 respectively

Given:

H allele (p) = hairy heffalump (dominant)

h allele (q) = hairless heffalump (recessive)

36% of heffalump population is hairless represents the % of recessive genotype, hh (q2) =36%

Calculation of frequency of the h allele (q) :

Frequency of genotype hh (q2) will be: 36/100=0.36 or 0.6*0.6

Frequency of h allele (q) will be 0.6
