yes
Yes, it is possible for a mother with A positive blood and a father with O positive blood to have a baby with A negative blood. The baby would inherit one A allele from the mother and one O allele from the father, resulting in A negative blood type.
Yes
I'll wait for you to ask the question. Positive parents can have a negative baby as positive is dominant so they may both have one positive and one negative gene and the baby gets the two negative genes.
A person with A positive blood may be a carrier for O negative blood. If the other parent is also a carrier of those traits, the baby could be O negative.
No
No, it is not possible.
No Danger At All, The Father Could Have A Positive Blood.
B negative
Yes, a mother with negative and a father with O positive can have a baby with B positive. If they do, the mother must have blood type B or AB.
Of course!
No. A positive O blood type means that each parent has two copies of the O blood type allele and can only give an O to their baby. The baby must have the blood type O. However, it can be O positive or O negative.
no cause a positive and negative make a negative unless the positive has a really strong blood line
