Suppose you have monohybrid snapdragons in your garden and you find that they produce red seeds to white seeds in the ratio of 3:1. If the alleles are designated R (red seeds) and r (white seeds), what are the probable genotypes of the snapdragons in your garden?

RR and Rr. Reason why, There are three Dominant genotypes and one recessive genotype. 3:1

anonymous · Answer

It's C because if its phenotype is 3:1 that means three of the seeds are red and one is white. Since white is recessive character symbolized as  "r" so white character is only expressed when both alleles are recessive "rr". Hope it is understandable.
