9. In pea plants, the allele for round seeds (R) is dominant over the allele for the wrinkled seeds (r). The following cross was made between two pea plants. RR x RR Identify the most likely genotype(s) of the offspring of this cross.

One-half the offspring will be RR, and one-half will be rr.

One-half the offspring will be rr, one-fourth will be Rr.

All the offspring will be RR.

All the offsring will be Rr.
