Answer:

Explanation

Given that 36% are recessive in traits

100-36 = 64% for dominant traits considering a whole population to be 100%

P=dominant allele

q= recessive allele

P2= dominant genotype

q2= recessive genotype

according to hardyweinberg principle, p+q=1

64/100= 0.64 frequency for dominant traits or genotype, therefore

p2=0.64

then

P=√0.64

p= 0.8

Therefore, dominant allele frequency (p) for the population is 0.8
