Suppose you have monohybrid pea plants in your garden and find that they produce round seeds to wrinkled seeds in the ratio of 3:1. If the alleles are designated R and r, respectively, what are the probable genotypes of the wrinkled seeds produced by your plants?

I think they would be "rr"
If the ratio is 3:1, then the offsprings would be:
RR Rr Rr and rr
Three would have round seeds (R being the dominant allele) and only one would be the rr (recessive)genotype.
