What percentage of the offspring will be Rr x rr
round? ___________
What is the genotypic ratio? What is the percentage of heterozygous offspring?
The genotypic ratio for the cross between Rr and rr would be 50% Rr and 50% rr.
Since the heterozygous genotype Rr represents half of the possible genotypes, the percentage of heterozygous offspring would also be 50%.
