We are looking for the possible blood types of a baby.

Parental information:

  • Mother type O pos = can only be OO and Rh (++) or (+-)
  • Father type B pos = can be BB or BO and Rh (++) or (+-)
Baby receives one gene from each parent:
  • Baby is type BO (++) = Type B pos
  • Baby is type BO (+-) = Type B pos
  • Baby is type BO (--) = Type B neg
  • Baby is type OO (++) = Type O pos
  • Baby is type OO (+-) = Type O pos
  • Baby is type OO (--) = Type O neg
YES, the baby of O pos and B pos parents can be blood Type O neg.

Since the ABO blood group system is codominant, the parent who is type O has both allels coding for type O. The parent who is AB has one allele coding for type A while the other allele is coding for type B. Although the child will inherit only the O allele from the type O parent, the child's phenotype will be either A or B. Since the child will inherit either the A or the B allele from the AB parent.

There is a high chance that positive blood will be made as both the O + and the AB + blood have the Rh antigens which make the blood positive.

The offspring of AB negative and B positive parents may be type A, B or AB, Rh positive or negative. Specific type depends on the genotype of the phenotypic B, Rh positive parent.
