In heritage carrots, colour is controlled by two alleles that show incomplete dominance. When pure-breeding purple carrots are crossed with pure-breeding white carrots, yellow carrots are produced. a) Provide the genotypes for the three colours of carrots, using proper notation. b) What is the phenotypic ratio expected when two yellow carrots are crossed? Include a Punnett square. I
