1. I can… analyze punnett squares! Warm up: What percentage of heterozygous offspring would there be from a parent that is homozygous dominant and a parent that is homozygous recessive? Make a punnett square!

8. Harry has dark hair like his father, but his mom had red hair. Using the genotypes of dd (red hair), Dd (dark/brown hair), DD (dark/brown hair), what possible genotypes does each of the Potters have?

9. Harry marries Ginny who has red hair. What are possible genotypes of their children’s hair colors?

10. Try a CODOMINANCE scenario: A purple flower is crossed with a white flower. In this species, white and purple are CODOMINANT traits. Show their punnett square. What are the phenotypes of the offspring? What are the percentage of the offspring will be homozygous?

11. Try an INCOMPLETE DOMINANCE scenario:
