A. 0.3

B. 0.7

C. 1

D. 0.009


2. If the frequency of p = 0.8, what is the frequency of the heterozygous genotype?


A. 0.16


B. 1.6


C. 0.32


D. 3.2

3. If the frequency of q of a trait is 0.4, what is the frequency of p?

A. 0.2


B. 0.4


C. 0.6


D. 1

Answer 1

1. Take the square root of p2 and subtract that from 1.
2. Find q from q=1-p, and then calculate 2pq.
3. p + q = 1
