Hardy Weinberg Equilibrium formula for allelic frequency is:
Hardy Weinberg Equilibrium formula for genotypic frequency is:
Here,=frequency of dominant allele
=frequency of recessive allele
=frequency of dominant genotype
=frequency of recessive genotype
=frequency of heterozygous genotype
frequency of affected individuals=0.0004(given)
here,affected individuals means the one's having Cystic Fibrosis and since it is recessive disease so we can write frequency of recessive genotype as: =0.0004
If =0.0004 will be 0.02;frequency of recessive allele will be 0.02
