And since it is an X-linked recessive trait, we're going to be dealing with the sex chromosomes. Contact Us. The Punnett square below shows the expected genotypes of the offspring of parent pea plants that both have the genotype Rr. How to do a Punnett square? Every individual has two chromosomes with two alleles that make their genotype so it is represented with two letters.
