The frequency of individuals born in a population with PKU is q2. There is one PKU (q2) birth per 10,000 births. The frequency of the recessive allele for PKU in this population is q = 0.01. The frequency of the dominant allele in this population is p = 1 - q = 0.99. What is the frequency of carriers (2pq) in this population?

Quizplus · Accepted Answer

We know that p + q = 1. Therefore, p = 0.99 and q = 0.01.

To find the frequency of carriers (2pq), we can use the formula:

2pq = 2(0.99)(0.01) = 0.0198

So the frequency of carriers in this population is 1.98%, which rounds up to 2%. Therefore, the best choice is B.
