Santa Claus and Mrs. Claus are expecting a little bundle of joy soon. Santa Claus is homozygous for good vision. Mrs Claus is ne
arsighted, which is a recessive trait. They want to know if their baby will need glasses in the future. Help them find the possible genotypes and phenotypes of their new baby
Santa= AA Mrs Claus= aa ----------------------- PARIENTAL: AA x aa Gamets: A A x a a F1: Aa ,Aa,Aa,Aa -100% good vision Pariental 2: Aa x Aa Gamets: A a x A a F2: AA Aa Aa aa so we have here 75% good vision,25% bad vision which is 3:1 and we have 1 dominant homozygous,2 dominant heterozygous and 1 recessive homozygous,which is 1:2:1.
