Yes, with a percentage reaches only to 25%.
Yes, they can.
Yes.
No, an O-group parent cannot have an AB-group child at all.
Yes they can.
Yes, it is possible for parents with blood type O positive and B positive to have a child with B positive blood type. The child could inherit one B allele from the parent with blood type B and either an O or B allele from the parent with blood type O, resulting in a B positive blood type.
Yes. parent with B and a parent with O blood traits can have the following blood types in their children : B, O, BO
yes
Yes, an AB negative (AB-) and an O positive (O+) individual can have a baby with a B positive (B+) blood type. The possible blood types of their child can be A, B, AB, or O, depending on the combination of alleles inherited from each parent. Since the AB parent can contribute A or B alleles, and the O parent contributes an O allele, a B blood type is possible if the child inherits a B allele from the AB parent and an O allele from the O parent. Additionally, the Rh factor from the O+ parent can result in the child being Rh positive or negative.
No, an O-group parent cannot have an AB-group child at all.
No. The child will be type B or O, it cannot be type A.
No, A positive and O positive parents cannot have a B positive child biologically. The A and O blood types do not carry the B antigen needed for a child to have a B positive blood type. Each parent would need to carry at least one B allele to pass it on to their child.
Yes - if both are heterozygotic for RH factor.
