No. The mother must be either AO or AA, and the father OO. No combination of these can give rise to an AB child. However, a negative mother and a positive father can have a negative child, by rhesus factors, if the father has genotype +-.
The child would be AB plus, so yes.
Barack is type AB, so there are several possibilities: Mom A, Dad B Mom B, Dad A Mom AB, Dad A Mom AB, Dad B Mom A, Dad AB Mom B, Dad AB Mom AB, Dad AB
No
yes.
no
If my mother is b- and my dad is b+ could there be a child ab- please
You could potentially be: A Positive B Positive AB Positive A Negative B Negative AB Negative
Sure.
No to have an AB child the parents must have an A allele in one ine parent and a B in the other so that when they reproduce those two alleles (foumd on the chromosome) can be passed to the offspring and hence the child will be AB blood group. As the father is O (which is a recessive allele) he cannot have either an A or B allele and so the offspring will always have one O allele and either the A or B allele from the mother. The child cannot be AB.
yes! Yes, because both of the parents can put a B over into their baby's blood type. You don't mention it, but the father would either be a BB or BO. If he is BO, then their children could be AO(A) , BO(B), BB, AB...because they are taking one from each parent. If the father is BB, then their kids would be AB , or BB's (B)basically. They would all be positive blood type.
Yes. If you cross parents with AB and O, you can have children with either A or B blood types.
