Is it possible for a mother to have a positive blood type and father b positive to have a baby with ab negative?
Yes -- There is not one gene that determines blood type. The father can be heterozygous for the A blood type. This just means that the father has one A gene and one O gene. Since the A gene is dominant, the blood from the father tests as A. A separate gene determines the positive and negative part of the blood grouping. This is the RH factor. Again the father can have one gene that is positive and one that is negative, positive is dominant.
Same analysis for the mother, mixed B and O genes with B as dominant, positive and negative for RH factor, positive dominant.
The egg from the mother could contain the B and RH negative (50% chance of each). The sperm from the father could contain the A and RH negative. Thus the baby would be AB negative (no positive from either parent).
What else can I help you with?
If mother is positive and father is negative is it possible the child would be negative?
If mother is heterozygote yes.
Your father has a positive blood and your mother has o positive and you have a negative is this possible?
yes
Is it possible for a child to have O negative blood if the mother has A positive blood and the father has A positive blood?
No.
Can a b positive father and o negative mother have a b positive baby?
yes its possible
Is it possible for an AB negative mother to have a baby with an o positive father?
yes
Is b-pos be the father to a-pos?
Yes it is possible if the mother is A positive or A negative.
Can a child be negative if the mother if positive and father is negative?
Yes, this is possible. only if the mother's alleles are Heterozygous (Rh+Rh-).
Can a o negative mother and a positive father have a a positive child?
If the mother's genotype is AO, then it is possible that the child can be type O-
If the father is a positive and the mother is o positive what would the child's blood type be?
A positive, O positive, A negative, or O negative; all are possible
Can a A positive mother and a O positive father have an O negative child?
If the mother's genotype is AO, then it is possible that the child can be type O-
Can a mother with A positive blood and father with O positive blood have a baby with A negative blood?
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.
Is It Possible for a child to have O positive with father A Positive and mother A Negative?
Yes, if both parents have genotype AO.
