Question

question 2 of 10
a trait has two alleles, represented by p and q. if p = 0.35, what is q?
a. 0.65
b. 0.59
c. 0.35
d. 0.42

Explanation:

Step1: Recall the Hardy-Weinberg principle

For a trait with two alleles, the sum of the frequencies of the two alleles \( p \) and \( q \) is equal to 1, i.e., \( p + q = 1 \).

Step2: Solve for \( q \)

Given \( p = 0.35 \), we substitute into the equation \( p + q = 1 \). So, \( q = 1 - p \).
Substituting the value of \( p \), we get \( q = 1 - 0.35 = 0.65 \).

Answer:

A. 0.65
