In pea plants, flowers are either white or purple; the purple color is produced by pigments called anthocyanins. The production of anthocyanins is a two-step process; the first is controlled by the C gene and the second by the P gene
Both genes must produce functional
proteins for anthocyanin to be produced. For each gene, the dominant (C and P) alleles
produce functional proteins. You cross two pea plants, each with the genotype CcPp. What
proportion of their offspring will have white flowers?
A. 13/16
B. 9/16
C. 7/16
D. 3/4
E. 1/4
C
