If my husband blood type is b negative and my blood type is o positive what will the baby blood type be?

B or O: B- father with O+ mother can have multiple blood type possibilities for the following offspring blood types: Heterozygous O+/O- mother and B- father: B+, B-, heterozygous O+/O- (phenotype O+), homozygous O-/O- (phenotype O-). Homozygous O+/O+ mother and B- father: B+, and heterozygous O+/O- (phenotype O+). Hope this helps.

It can be either: B or O, positive or negative, depending on which 2 genes you both carry. Your husband may have 2 B genes, or a B and an O gene. You may have two positive genes or a positive and a negative gene. B+O would equal B, O+O would equal O. Negative + negative = negative, while negative + positive = positive. It depends on what you both carry and what you pass on!

Depends: Assuming you and your husband are the biological parents, your baby could have several possible types - B +, B -, O+, or O -. If you used donor eggs, donor sperm, or had a donor embryo implanted, the baby could have, literally, any blood type, based on the blood types of the biological mother and father.
