Respuesta :

Histrionicus

Answer:

The correct answer is -  1:1:1:1.

Explanation:

Mendel performed cross in between  peas with round, green seeds (RRyy) with peas having wrinkled, yellow seeds (rrYY)

                          gametes : Ry and rY

                                                 ↓

            F1 :                            RrYy

Test cross is the cross between f1 offspring and recessive parent which is

                    gametes : RY, Ry, rY, ry and ry

                                                             ↓

                                    F2 : RrYy, Rryy, rrYy, and rryy.

So, the phenotypic ratio of the offspring would be - 1:1:1:1.
