Answer 2

Answer:

The probability of having wrinkled seed and yellow seed color for the cross RRYY and RrYy is zero.

It is because the cross between RR and Rr will result in the production of offspring, all with dominant trait i.e. round seeds.

Hence, the probability of rr would be zero and so the probability of wrinkled seed with green seed color would be zero.

It can also be explained with the help of punnet square as provided in the figure attached.
