What blood type parents make O positive?
The ABO Blood Types
A child with type O blood can have parents with type A, type B, or type O blood, but not type AB. Conversely, if two parents both have type O blood, all their children will have type O blood.
How does a child get Type O blood?
If the Mother’s blood type is B, and the father’s blood type is O, then their child must be either B or O. For instance, if both mother and alleged father have type A blood, then the child can only have A or O blood.

There’s also another categorization for blood that the blood type diet doesn’t account for. Your blood may or may not have a protein known as Rh. This results in there being eight different types of blood. Type O-positive blood is the most common type, meaning you have O blood with an Rh factor.

Can a child have type O blood if parents have A and B?
If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.
