Purple flowers are dominant over the white flowers. The parent generation includes two heterozygous parents. What are the possible phenotypes of these parent offspring

Purple and white-flowered individuals.

Explanation:

First, let P represents the allele for purple flower trait and p for white flower trait. PP and Pp would be purple and pp would be white flower individuals.

The parents are two heterozygous individuals, Pp.

                     Pp    x    Pp

offspring:  PP    Pp    Pp    pp

PP and Pp = purple

pp = white.

Hence, the possible phenotypes of offspring from two heterozygous parents are purple and white-flowered individuals.
