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.

<em>Hence the phenotypes would be:</em>

<em>20 large size leaves plants</em>

<em>40 medium sized leaves plants</em>

<em>20 small sized leaves.</em>
