Question

if the frequency of q of a trait is 0.4, what is the frequency of p? 0.2 0.4 0.6 1

Explanation:

Step1: Use the Hardy - Weinberg principle

In the Hardy - Weinberg principle, for a gene with two alleles \(p\) and \(q\), \(p + q=1\).

Step2: Solve for \(p\)

Given \(q = 0.4\), substitute into the formula \(p=1 - q\).
\(p=1 - 0.4\)

Answer:

\(0.6\) (the third option)
