2 alleles are present, but neither allele is dominant. A petunia plants genotype is R1R1 and has red flowers. A plant that has the genotype R2R2 has white flowers.
Heterozygous individuals ( R1R2) have pink flowers.
If a white-flowered plant is crossed with a red-flowered plant what are the phenotypes of the offsping?
What are the genotypes?

R1R1 x R2R2
all the offsprings will be heterozygotes,genotypicallly R1R2 and as the character displays incomplete dominance all of them will be penotypically pink.

R1R1 with R2R2 would have a 100% chance of producing an R1R2 plant.
The phenotype (what it looks like) is Pink flowers.
The genotype is R1R2

Why are you trusting complete strangers to do your homework for you? Are you so dumb that you can't spend just two or three minutes thinking about this problem? Even if you guess and get it wrong, you will ultimately learn from your mistake. Copying down someone else's bulls**t doesn't teach you anything.
