Question

a trait has two alleles, and their frequencies are represented by p and q. if p = 0.42, what is q?
a. 0.76
b. 0.42
c. 0.65
d. 0.58

Explanation:

Step1: Use the Hardy - Weinberg principle

In the Hardy - Weinberg principle, for a trait with two alleles, \(p + q=1\), where \(p\) is the frequency of one allele and \(q\) is the frequency of the other allele.

Step2: Solve for \(q\)

Given \(p = 0.42\), substitute into the formula \(q=1 - p\). So \(q = 1-0.42=0.58\).

Answer:

D. 0.58
