In Mendel's experiments with garden pea, round
seed shape (RR) was dominant over wrinkled
seeds (rr), yellow cotyledon (YY) was dominant
over green cotyledon (yy). What are the
expected phenotypes in the F2 generation of the
cross RRYY × rryy ?
- ARound seeds with yellow cotyledons, and wrinkled seeds with yellow cotyledons
- BOnly wrinkled seeds with green cotyledons
- COnly wrinkled seeds with yellow cotyledons
- DOnly round seeds with green cotyledons

Correct answer: A
Since round seed shape is dominant over wrinkled seed shape and yellow cotyledon is dominant over green cotyledon so RRYY individuals is round yellow and rryy is wrinkled green.
