    The blood type of a child depends on the blood type of the parents. Each parent/person has two genes that make up the blood type. Depending on which combination each parent has determines the different combinations that the child can have. For example, if the mother is AO (received A from one parent and O from the other) and the father is BO there is a possibility that their child will have one of the following blood types: A (25%), B (25%), O (50%), or AB (25%).
