In pea plants, smooth pea shape is dominant towrinkled and yellow pea color is dominant togreen. a plant that is heterozygous for pea shape and has green peas is crossed with a plant that is has wrinkled peas and is heterozygous forpeacolor. what is the probability of having offspringwith wrinkledgreen peas?

The probability of having wrinkled green peas is 25% or 0.25

Explanation:

Given:

Pea shape - smooth and wrinkled

Pea color - Yellow and green

Smooth is dominant to wrinkled

Yellow color is dominant to green

So, the genotype of smooth pea is SS or Ss

                                 wrinkled pea is ss

The genotype of yellow pea is YY or Yy

                                 green pea is yy

According to the question,

Ssyy X ssYy

Possible gametes of Ssyy - Sy , Sy, sy, sy

Possible gametes of ssYy - sY, sy, sY, sy

Cross between these gametes are shown in the punnett square drawn in the word file attached.

According to the cross,

The probability of having wrinkled green peas is 25% or 0.25
