what blood type can be found in an offspring if a mother has type o blood and the father has type b blood

If the mother has type O blood and the father has type B blood, the child can only have either type B or type O blood.

Quick Scoop

• Type O means the mother’s genotype is OO (she can only pass an O allele).

• Type B can be either BO or BB for the father.

So the possible combinations are:

• If dad is BO :
  • Child could be BO → blood type B.

* Child could be **OO** → blood type O.

• If dad is BB :
  • Child will always be BO → blood type B.

That means:

• Possible offspring blood types: B or O only (no A or AB).

In simple terms: a type O mom can only “give” O, and a type B dad always “gives” B or O, so the child ends up B (if they get dad’s B) or O (if they get dad’s O).
