How do you get O positive blood type?

Everyone has an ABO blood type (A, B, AB, or O) and an Rh factor (positive or negative). 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.

To be O, you usually need to get an O from both mom and dad. But an AB parent usually has an A and a B version, not an O. So they usually can’t have an O child.

Can two a positive parents have an O negative child?

Yes, Mom or Dad may be positive, but that recessive negative gene is still floating around in his or her DNA. If it becomes paired with another negative gene from a similar positive-negative parent, that child will be negative even though both parents are positive. It’s an everyday occurrence, says pediatrician Dr.
