Two Type 0 can have a B
Yes Yes, two people with 0 blood can have a baby with B blood type. This is possible because the blood type gene is inherited in an autosomal recessive pattern. If both parents have the O allele (Oo), they can pass down the O allele to their child, resulting in the child having B blood type. The child will have two O alleles, which will mask the presence of the B allele, leading to the B blood type.
