Round seeds (r) are dominant to wrinkled seeds (r), and yellow seeds (y) are dominant to green seeds (y). a true-breeding plant with round and yellow seeds is crossed to a true-breeding plant with wrinkled and green seeds. what is the genotype of the f1 progeny?

RrYy ( all yellow seeds).

Explanation:

Mendel is known as the father of genetics. He explained the concept of dominance, law of segregation and law of independent assortment by crossing the pea plants.

A true breeding plants has been crossed with ( RRYY ) round and yellow seeds with rryy ( wrinkled and green seeds). Their cross can be shown as below.

Parents  RRYY    ×     rryy

Gametes    RY              ry

F1 progeny       RrYy ( All round and yellow seeds)

Thus, the genotype of the progeny is RrYy.
