Yes....if both parents are carriers of type "O" then they have a 25% chance of having a child with type "O" blood type (O is a recessive trait). The child would have to receive the recessive "O" from both parents. Regarding the Rh factor. If mom is a carrier of the negative Rh factor, then there is a 50% chance that the offspring may carry the Rh negative factor. Hope this helps...
With a mother with AB Positive blood type and a father with an O Positive blood type, there are four possibilities for the offspring's blood type. The child of this pairing could have A positive or negative, or B positive or negative type blood.
no
No. It is impossible, given those blood types, for the offspring to be O positive.
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 indeed.
Yes, a father with A negative blood can have a child with A positive blood. If he does, the mother must have a positive Rh factor, and the mother's blood type may be any of the possibilities.
O
yes, 2 positives can have a negative, but not the other way around. I have a son like that.
more than 99% not.
I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
No
