Kip studies flower color in petunias, where the allele for red flowers, R, is dominant to the allele for white flowers, r. If Kip makes the cross RR x rr, the gametes that are produced

An RR parent can produce only gametes carrying R, while an rr parent can produce only gametes carrying r. Therefore, the gametes from one parent carry R and those from the other carry r, as choice C states. Each offspring would receive one allele from each parent and have genotype Rr.
