A. The percentage of butterflies in the population that are heterozygous.

.4 is the frequency of white (bb) butterflies. This is q2
taking the square root of .4 gives you q = .63

1-.63 = .37; this is p

2pq = .47 (number of heterozygotes)

B. The frequency of homozygous dominant individuals. p2 = .14
