Question

A population of spotted deer found in a national forest is in Hardy-Weinberg equilibrium. For a
particular genetic locus in this deer species, only two alleles A and a are possible. If the frequency
of the A allele in this population is 0.6, and the frequency of the a allele is 0.4, what will be the
frequency of the genotype Aa?
(A) 0.24 (B) 0.48 (C) 0.96 (D) 1.6

Answer 1

AA=0.6
aa=0.4
Aa=?
(AA) the whole square+2Aa+(aa) the whole square =1
0.6)whole square+2aA+(0.4) whole square =1
0.36+2Aa+o.16=1
0.52+2aA=1
2Aa=1-0.52
2Aa=0.48
