In Mendel's experiments with garden pea, round seed shape (RR) was dominant over wrikled seed (rr), yellow cotyledon (YY) was dominant over green cotyledon (yy). What are the expected phenotypes in the F2 generation of the cross R R Y Y- rryy?

Question

In Mendel's experiments with garden pea, round seed shape (RR) was dominant over wrikled seed (rr), yellow cotyledon (YY) was dominant over green cotyledon (yy). What are the expected phenotypes in the F2 generation of the cross R R Y Y- rryy? (A) round seeds with yellow cotyledons, and wrinkled seeds with yellow cotyledons (B) only round seeds with green cotyledons (C) only wrinkled seeds with yellow cotyledons (D) only wrinkled seeds with green cotyledons

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.

Q. In Mendel's experiments with garden pea, round seed shape (RR) was dominant over wrikled seed (rr), yellow cotyledon (YY) was dominant over green cotyledon (yy). What are the expected phenotypes in the F2​ generation of the cross R R Y Y- rryy?

round seeds with yellow cotyledons, and wrinkled seeds with yellow cotyledons

only round seeds with green cotyledons

only wrinkled seeds with yellow cotyledons

only wrinkled seeds with green cotyledons

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.

Q. In Mendel's experiments with garden pea, round seed shape (RR) was dominant over wrikled seed (rr), yellow cotyledon (YY) was dominant over green cotyledon (yy). What are the expected phenotypes in the $F_{2}$ generation of the cross R R Y Y- rryy?
