In Drosophila, normal eyes are brick red in color. Homozygotes for recessive alleles at the brownlocus (bw/bw) have brown eyes. Homozygotes for recessive alleles at the cinnabar locus (cn/cn) have bright red eyes. The two genes interact: bw/bw; cn/cn have white eyes. If a pure-breeding brown is crossed to a pure-breeding cinnabar fly, color eyes will the F1 have and what proportion of the F2 will be white?

A. brown, 3/16

B. brick red, 9/16

C. bright red, 3/16

D. brick red, 1/16
