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 inheritance

For seed shape, the cross is \(RR\times Rr\). Using the Punnett - square or the rules of Mendelian genetics (dominant - recessive inheritance), \(RR\times Rr\) gives \(Rr\) and \(RR\) offspring. The probability of getting \(rr\) (wrinkled, recessive) is \(0\) since the first parent \(RR\) can only contribute \(R\) allele.

Step2: Analyze seed color inheritance (though it's not necessary for the final result in this case)

For seed color, \(YY\times Yy\) gives \(YY\) and \(Yy\) offspring. The probability of getting yellow - seeded (\(YY\) or \(Yy\)) is \(1\) (since \(Y\) is dominant for yellow color). But since the seed - shape part already makes the probability of having wrinkled seeds (\(rr\)) zero.

Answer:

A. 0 percent
