Question

In a population of 1000 individuals 360 belong to genototype AA ,480 to Aa and the remaining 160 to aa Based on this data ,the frequency of allele A in the population is
A. 0.6
B. 0.7
C. 0.4
D. 0.5

Answer 1

Correct Answer - A
(a) According to Hardy Weinberg principle
`P^(2)`+2pq+q^(2)=1,(p+q)^(2)=1`
(AA) `P^(2)=360` out of 1000 individual or `P^(2)=36` out of 100
`q^(2)=160`out of 1000 or `q^(2)=16` out of 100
so, `q=sqrt(.16)=.4. As" "p+q=1`
so, p is 0.6.
