B) Assume that Ay is a dominant allele that codes for purple leaves and A2 is a recessive allele that codes for white leaves. What will be the frequencies of purple and white phenotypes in this population?

All plants of purple colour.

Explanation:

All the offspring plants of F1 generation have purple leaves because Ay is dominant allele which appear in the leaf colour instead of A2 which is a recessive allele. In the F1 generation, the dominant allele must appear in the shape and structure of the offspring whereas the recessive allele does not appear so offspring of purple leaves appear if plants have purple leaves cross with white leaves.
