Question

In peas, a gene controls flower colour such that R = purple and r = white. In an isolated pea patch, there are 36 purple-flowering plants and 64 white-flowering plants. Assuming Hardy-Weinberg equilibrium, what is the frequency of the r allele for this population?

A. 0.36
B. 0.64
C. 0.75
D. 0.80

Answer 1

Answer:

The frequency of the r allele in this population is 0.80

Explanation:

64+36=100 plants

Frequency of White Flowering plants(rr) = 64/100

rr = 0.64

r is calculated by finding the square root of 0.64 which gives 0.80.
