Directions: Use the Punnett Squares from the previous problems to answer these follow up questions. 1. Based on problem #1, if one seed was chosen from the offspring to perform a new experiment on and I had to select a mate that would cause the offspring to have the same phenotypes as the grandparents, what would be the genotype of that new mate? Show why your answer works using a Punnett Square. Offspring's genotype New mate's genotype

1. In pea plants, round seeds (R) are dominant to wrinkled seeds (r). A homozygous dominant plant was
mated to a homozygous recessive plant for this trait. Complete a Punnett Square and report the
