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.
The answer would be E because boys inherit the Y chromosome from the dad which in this case would have the color blind trait. Girls don’t get the y from the father to get the color blind trait not be color blind because girls have 2 (X) chromosomes. Hope this helps
Yes because brown eyes are a dominant gene while blue is recessive gene so one of both of the parents ancestors had to have them for her to be their biological daughter.
