Theoretically :
If mother AB+ ( with hetero alleles Rh+Rh-) children are :
A+,A-,B+,B-
If mother AB+ ( with homo alleles Rh+Rh+) children are :
100% A+,B+
Given that the mother's DNA is A and the child is A positive, the father's DNA must also contain the A antigen. The father could be A positive, A negative, AB positive, or AB negative.
for sure
yes it dependsupon the genotype and phenotype
You dad can either be O, AB, A,or B and he can be positive or negative.
Yes, it is possible for parents who are AB positive and B positive to have a child who is A negative. This is because a child can inherit one A and one Rh negative gene from the parents, resulting in blood type A negative.
If the mother is A negative, and the father is B positive, they could have children who are A negative, A positive, B negative, B positive, AB negative, AB positive, O negative, or O positive.
# yes, if father is + - for RH and mother - - (negative) or + - (positive); the father can generate sons A, B, or AB depending by mother's group.
Given that the mother's DNA is A and the child is A positive, the father's DNA must also contain the A antigen. The father could be A positive, A negative, AB positive, or AB negative.
it could be a- or ab+
yes. mother can be ab negative.
No, the father would have to have B or AB.
Yes.
yes
for sure
No, i don't think so.
yes
An AB+ and B- couple can't have a child with blood type O. They can have children with blood types A, B, or AB, and can have children with Rh negative or Rh positive blood.
