Answer:

The correct option is B. Rr × rr

Explanation:

To illustrate the results, lets make a cross between RR and rr.

      r         r

R    Rr       Rr

r      rr        rr

   

The results from the following punnet square show that there will be a 50% probability that the offsprings will have heterozygous genotype Rr and they will be round.

The results from the punnet square show that there will be a 50% probability that the offsprings will be recessive and hence will have wrinkled seeds.
