D. Sex-linked In humans, hemophilia is a sex-linked trait. Females can be normal, carriers, or have the disease. Males will either have the disease or not (but they won't ever be carriers). 1.

She is worried because they are pregnant and their future child has a rare disorder which will require him to need regular blood transfusions. Jess worries that if their son ends up with type O blood, like his father, it will be hard to get the necessary regular blood transfusions because people with O blood can only accept O blood.

A couple decide to have a child. They require and select a suitable sperm donor who they understand to be blood group AB and rhesus +ve. The carrier of the baby is blood group A and rhesus –ve. However, when the baby is born, they discover that the baby’s blood group is O rhesus +ve. Worried that there has been a mistake they ask for a DNA test, which confirms the sperm used was indeed that of the donor. Further DNA analysis of the carrier of the baby shows that she has isoagglutinogen alleles IA iO, while the baby is actually IB and IO. How would you explain the outcome of the blood group to the couple? What is the chance that any other children will be blood group O using the same sperm donor? What further medical considerations should the couple consider for this child and additionally for any other subsequent pregnancies?
