A member asked:

If a mother has type o + blood and father is b+ or negative what are the possibilities for the child's blood type?

A doctor has provided 1 answer

Depends: First, dad must be either Rh+ or -, he can't be both. Your O type means you have 2 genes for O. His B type could be both B genes or one B and one O. Your offspring could be either O or B depending on what genes he carries. The Rh wouldn't matter at least during the pregnancy.
