Answer #1

given

allele frequency = 0.6 ( p)

according to hardy weinberg equilibrium

p+q = 1

so q = 0.4

genotype frequency of individuals that are homozygous for the recessive trait is given by q2

p^2+2pq+q^2=1

where p^2 = Frequency of AA (homozygous dominant) individuals

q^2 = Frequency of aa (homozygous recessive) individuals

2pq = Frequency of Aa (heterozygous) individuals.

therefore q2 = 0.4*0.4 = 0.16

that is 16%

e) 16% is correct answer.

Please thumbs up if this answer helped you in any way. Thanking you in anticipation.
