Does the father’s blood type matter in pregnancy?

Can siblings have different blood types?
While a child could have the same blood type as one of his/her parents, it doesn’t always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B. These two types are definitely different than parents’ blood types!
How do you get O blood type?
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.
Can a child have different blood type than parents?
Yes, a child is able to have a different blood type than both parents. Which parent decides the blood type of the child? The child’s blood type is decided by both parents’ blood type. Parents all pass along one of their 2 alleles to make up their child’s blood type.

Could a man with O blood type be the father of an AB child?
For example, two O blood type parents can produce a child with only O blood type. Two parents with A blood type can produce a child with either A or O blood types….PATERNITY CAN BE RULED OUT BASED ON BLOOD TYPE MATCHING IN MANY CASES.

Can a child have type O blood if parents have A and B?
A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).
