Question

When true breeding yellow wrinkled seeded pea plant is crossed to true breeding green round seeded pea plant the progeny is?

Answer 1

As yellow seed and round seed are dominant characters means cross is between YYrr × yyRR
all the progeny will be yellow and round
genotype will be YyRr

Answer 2

Answer:

The progeny produced is a round and yellow-seeded (YyRr) plant.

Explanation:

Given data says,

the true-breeding round green seeded plant of pea (RRyy) is crossed with the yellow wrinkled seeded plant (rrYY) which means: RRyy× rrYY

 Parents:   RRyy ×  rrYY

                                 

gametes:     Ry    ×       rY

                            ↓

F₁ gen.:          YyRr (all round and yellow seeded plants)

• Thus when the true-breeding yellow wrinkled seeded pea plant is crossed to the true-breeding green round seeded pea plant the progeny obtained are all round and yellow seeded plant.

• This represents the Mendelian law of dominance which expresses the dominant character in the F₁ generation. This expresses the dominance of yellow and round seeds over wrinkled green seeds.
