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

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

Answer

Answer:

A. 0 percent

Explanation:

Step1: Determine gametes

The RRYY parent can only produce RY gametes. The RrYy parent can produce RY, Ry, rY, ry gametes.

Step2: Set up Punnett - square

A Punnett - square with 1 type of gamete from RRYY (RY) and 4 types of gametes from RrYy (RY, Ry, rY, ry) will have the following combinations: RRYY, RRYy, RrYY, RrYy.

Step3: Analyze phenotypes

Since round (R) is dominant over wrinkled (r) and yellow (Y) is dominant over green (y), there are no offspring with the genotype rrY_ (which would give wrinkled seeds and yellow seed color). So the probability is 0 percent.
