In the following image, which symbols (genotypes) are involved in the cross to produce the f2 generation of pink flowers?

The dominant RR (red) and recessive rr (white). The color pink seems to be an intermediary between the dominant and recessive parent. Thus a heterozygote (Rr) that contains both a dominant and recessive gene will have a pink color.

Your answer should be Rr x Rr. But i'm not completely sure so check with a teacher or parent.
