Flower Color in Peas? 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 expressed. 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?
Interpret the results of mendelian test cross with respect to flower colors
The proportion of their offspring will have white flowers is 7/16
The production of anthocyanins is controlled by dominant C and P gene. Thus, absence of one or both dominant C or P results in white flowers. According the cross that is shown in image, the answer is 7/16
