melamori03 [73]

Answer:

The correct answer is b. All round seeds

Explanation:

If an RR plant is crossed with an rr plant than all the phenotype will produce round seed and the frequency of the Round seed plant to wrinkled seed plant would be 4:0.

                       R     R

                  r   Rr    Rr

                  r   Rr    Rr

So all the phenotypes will be heterozygous dominant for the round seed which means that all phenotypes will have a single dominant allele for round seed which is enough to express round seeds in the phenotypes.
