Of course, you got your blood group from one of your parents or one of your grandparents.
Yes, an AB negative father can parent an A positive child. However, in order for this to happen the mother would need to be positive.
No. Since both are Rh positive, the child will be Rh positive.
The child will be A or B or AB, Rh+ or Rh- . So yes, the child can be A-.
No, an O-group parent cannot have an AB-group child at all.
No. The mother must be either AO or AA, and the father OO. No combination of these can give rise to an AB child. However, a negative mother and a positive father can have a negative child, by rhesus factors, if the father has genotype +-.
Yes it is possible...
No. If the child is AB, it must have inherited the A from one parent and the B from the other. If the father is O he has OO - and so cannot give the child an A or B.
No, an O-group parent cannot have an AB-group child at all.
yes
yes it dependsupon the genotype and phenotype
No, the father would have to have B or AB.
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
AB+
