Question

The incidence of cystic fibrosis, a recessive genetic disorder in the Caucasian population of United States, is 1 in every 2,500 individuals. Find the number of heterozygous carriers.
(p + q = 1, p2 + 2pq + q2 = 1)

A:0.0392
B:0.0254
C:0.045

Answer 1

This is not my strong point, but I would think that q2 = 1/2500, so q = sqrt(1/2500) and you can work it out from there.

Answer 4

c is incorrect
