Question

The following genotypes are found in population AA:Aa:aa =60:20:20.What are the allie frequency of A and a ?​

Answer 1

Answer:

A=0.7,a=0.3

Explanation:

let the dominant allelic frequency=A=60

a=20

and heterozygous=20

formula

let ratios as it is total for 100 individual s

A=2×no.of dominat individuals+no.of heterogeneous individuals /2×total no.of individuals

=2(60)+20/2×100

=140/200

=0.7

you can use the same formula for reccesive or direct formula A+a=1

therefore,

a=1-0.7

=0.3
