Question

round seeds and yellow seed color are dominant to wrinkled seeds and green seed color. what is the probability of having offspring that have wrinkled seeds and yellow seed color for the cross rryy × rryy?
○ 0 percent
○ 25 percent
○ 50 percent
○ 100 percent

Explanation:

Step1: Analyze seed shape

For seed shape, \(RR\times Rr\). The possible genotypes of offspring are \(RR\) and \(Rr\). Since \(R\) (round) is dominant, there is no offspring with wrinkled seeds (\(rr\)).

Step2: Analyze seed color

For seed color, \(YY\times Yy\). The possible genotypes of offspring are \(YY\) and \(Yy\). All offspring will have yellow seeds as \(Y\) (yellow) is dominant.

Since there is no way to get wrinkled seeds (\(rr\)) from the cross \(RR\times Rr\) for the seed - shape trait, the probability of having offspring with wrinkled seeds (regardless of seed - color) is \(0\).

Answer:

0 percent
