1. (5 Pt) In garden peas, Mendel found that yellow is dominant over green, and round shape is dominant over wrinkled. What are the different gametes possible in a cross between a homozygous (YYRR) plant and a homozygous (yyrr) plant? What is the genotype and phenotype of F1 offspring? What are the possible F2 genotypes and phenotypes? Show the F2 results in a Punnett square.
2. (2.5 Pt) Show the results of a cross between a colorblind male and a heterozygous female (carrier) using a Punnett square. How many of their children are colorblind or carriers?
3. (2.5 Pt) Show the results of a cross between a normal male for color vision and a heterozygous female (carrier) using a Punnett square. How many of their children are colorblind or carriers?
