Yes, the father can be pretty much any blood type... If the baby has blood type O, he or she must have gotten an O from each parent. This means the mother with blood type A is of variety AO. The father must also have contributed an O, which means he must have AO, BO, or OO blood type. The father cannot have AB blood type.
No.
NO
Yes, it is possible for both mother and father to be RH positive and a child to be RH negative.
Possible blood types of the child with a mother who has A blood type and a father who has AB blood type are A, B, and AB. :)
Yes, it would be possible if the mother had type A blood.
Yes, it is possible for a heterozygous mother with blood type A to have an O blood child when the father has blood type AB. This occurs because the mother provides an O allele and the father provides a recessive O allele, resulting in the child having blood type O.
Yes, it is possible for a mother with AB blood and a father with O blood to have a child with O blood type. This is because the parents can each pass on an O allele, resulting in a child with O blood type.
No
Yes, It is possible. But most of the time the child would have the same type of blood.
Yes, it is possible for a child to have a different blood type than their father. A child inherits one blood type allele from each parent, so if the child receives a B allele from their mother and an A allele from their father, they can have blood type B.
It depends. If the mother of the child is A positive as well, the child will be A positive. This is also true if the mother is a type O. It wont be possible if the mother is B positive, since the child will be AB positive (the blood types are codominant).
Yes
