In peas, the allele for round seeds (r) is dominant to the allele for wrinkled seeds (r). what would be the genotype and phenotype ratios of offspring from a cross between rr and rr individuals?
I believe you meant the allele for round seeds (R) is dominant to the allele for wrinkled seeds (r). The cross between RR and rr is all Rr, all will have rounds seeds.
