Question

There is a population of Drosophila flies in a small fruit shop. Due to sudden mutation, the eye color of some of the flies changes from red to white. Red (represented by R) is the dominant gene, and white (represented by r) is a recessive gene. Due to this, the gene frequency of allele r changes from 0.38 to 0.40.
What will be the new genotype frequencies in that population?
( p + q = 1, p2 + 2pq + q2 = 1)
A.) p2 = 0.36, 2pq = 0.48, q2 = 0.16
B.) p2 = 0.32, 2pq = 0.23, q2 = 0.45
C.) p2 = 0.25, 2pq = 0.36, q2 = 0.39
