Question

A fly has two alleles for the color of its eyes. The green allele is recessive, and is represented by q. The blue allele is dominant, and is represented by p. If 71 of 100 organisms are green, what is p?

a. 0.16
b. 0.29
c. 0.84
d. 0.71

Answer 1

To find the value of p, the frequency of the dominant blue allele, subtract the frequency of the recessive green allele from 1. In this case, p = 1 - 0.71 = 0.29.

Step-by-step explanation:

To determine the value of p (the frequency of the dominant blue allele), we need to first find the value of q (the frequency of the recessive green allele). Given that 71 out of 100 organisms are green, we can calculate the frequency of q by dividing the number of green organisms by the total number of organisms: q = 71/100 = 0.71. Since p + q = 1, we can find the value of p by subtracting q from 1: p = 1 - 0.71 = 0.29.

Therefore, the value of p is 0.29, so the correct answer is b. 0.29.
