It depends on what you both carry and what you pass on! ...Read more

What happens if two parent with o positive blood types have a child with b negative blood type?

Not possible: It is possible for the child to be rH negative if both parents are hybrid rH positive (one positive and one negative rH gene), but if they are both type O can only have type O children.

Do all negative blood types automatically have a negative Rh factor? (if you neg on one are u neg on other)

Do all negative blood types automatically have a negative Rh factor? (if you neg on one are u neg on other)

It's the same thing: In the abo/rh blood typing categories, if the rh factor is not there, it is called a negative blood type. (in other situations, when doctors are not talking about the abo/rh typing, then "negative" would mean that something else is missing. For example, a test for sickle cell anemia would be called "negative" if no sickle cell mutation was found, but would not be talking about the rh factor.). ...Read more
