Question

If PTC non taster population is 16 % then percent population of Heterozygous taster is

Answer 1

We know that 16% of the pop. is recessive so we call that q²
There is in fact 2 formulas needed : p² + q² + 2pq = 1(population) and p+q=1
AA aa Aa

so √q²=√.16 --> q= .4 --> so p= .6 when you subtract .4 from 1
What heterogeneous means is the Aa or 2pq. Since we already have p and q we just multiply them and then multiply that answer by 2
2(.6 x .4)= .48 = 48% of the pop/ is heterogeneous
