Answer 2

Hello!

Let genotype of Yellow be YY and genotype of green be yy.

Let Genotype of Round = RR and Genotype of wrinkled = rr

YYRR × yyrr ----›

Gamete formed in F1 generation is RrYy i.e. Round and Yellow

Now in order to obtain F2 generation we will do selfing

Selfing is shown in the above notes:-

Phenotype ratio :- 9:3:3:1
