A woman has been trying to conceive for several years, unsuccessfully. at a fertility clinic, they discover that she has blocked
fallopian tubes. using modern technologies, some of her eggs are removed, fertilized with her husband's sperm, and implanted into her uterus. the procedure is successful, but the couple discovers that their new son is color-blind and has blood type o. the woman claims that the child can't be theirs since she has blood type a and her husband has type b. also, neither parent is color-blind, although one grandparent (the woman's father) is also color-blind.
The women was a carrier of the color blind trait, its recessive so she passed the trait down on his only X chromosome, men are more likely to be color blind because they only have to have one faulty X chromosome. females have to have both X's wrong. and O is also a recessive trait so they had AO and BO blood types and the OO matched up for there baby
