Yes. It just means that both parents are heterozygous for rh factor, and each parent passed on the recessive rh negative allele to their child.
The blood would be A+, the child's is always pretty much what the Father's is.
Yes, if both the mother and the father are carriers of the recessive Rh negative trait, they can produce a child with O negative blood type. The child would inherit one Rh negative allele from each parent, resulting in a negative blood type.
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.
Yes, it is possible for a father with O negative blood type to have a child with O negative blood type. In genetics, the child inherits one blood type allele from each parent, so it is possible for the child to receive an O allele from both parents, resulting in an O negative blood type.
Not necessarily. A child's blood type is determined by the combination of both parents' blood types. If the father carries the A negative blood type, then it is possible for the child to be A negative as well.
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.
yes
I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
a-
No
more than 99% not.
There is a 75% chance the child will be A negative, and a 25% chance the child will be O negative.
yes.
No.
yes.
The blood would be A+, the child's is always pretty much what the Father's is.
If the mother has type negative blood, and the father and child have type positive blood, the mother's blood may begin to attack the child's.
