yes
If the mother and father are both type O, the baby cannot be type AB.
Can a-mother and o+ father have ab+ baby
Yes. The mother has to be OO And the father can be either AA or AO So the mother can give one of her O's to the baby and the father can give his O to the baby making it an OO.
yes. mother can be ab negative.
then the baby will be O plus, or AB plus , I think .
There are many possibilities, but two things are certain: at least one parent must be type A or AB, and at least one parent must be Rh + A child with blood type A+ can have the following combinations of parents: Mother A+, Father A+ Mother A+, Father A- Mother A-, Father A+ Mother A+, Father B+ Mother A+, Father B- Mother A-, Father B+ Mother A+, Father AB+ Mother A+, Father AB- Mother A-, Father AB+ Mother A+, Father O+ Mother A+, Father O- Mother A-, Father O+ Mother B+, Father A+ Mother B+, Father A- Mother B-, Father A+ Mother B+, Father AB+ Mother B+, Father AB- Mother B-, Father AB+ Mother AB+, Father A+ Mother AB+, Father A- Mother AB-, Father A+ Mother AB+, Father B+ Mother AB+, Father B- Mother AB-, Father B+ Mother AB+, Father AB+ Mother AB+, Father AB- Mother AB-, Father AB+ Mother AB+, Father O+ Mother AB+, Father O- Mother AB-, Father O+ Mother O+, Father A+ Mother O+, Father A- Mother O-, Father A+ Mother O+, Father AB+ Mother O+, Father AB- Mother O-, Father AB+
the baby may be A or O.
If we are talking about blood types, the father can be B or AB.
yes
yes
Father could be AB, but an O mother is OO. so, AB X OO AO and BO are the only possible alleles from this cross
yes of course
