The trait of medium-sized leaves in iris is determined by the genetic condition PP′. Plants with large leaves are PP, whereas plants with small leaves are P′P′. A cross is made between two plants each with medium-sized leaves. If they produce 80 seedlings, what would be the expected phenotypes, and in what numbers would they be expected?

20 large size leaves plants

40 medium sized leaves plants

20 small sized leaves.

Explanation:

PP = large leaves

P'P' = small leaves

PP' = medium leaves

PP' was crossed with another PP' plant:

PP'   x   PP'

progeny = PP, 2PP', and P'P'

PP = 1/4  x 80 = 20 large size leaves plants

PP' = 1/2 x 80 = 40 medium sized leaves plants

P'P' = 1/4 x 80 = 20 small sized leaves.

Hence the phenotypes would be:

20 large size leaves plants

40 medium sized leaves plants

20 small sized leaves.
