No, the RH factor is inherited from one parent.
A child with an A+ and O+ parent can only have A+ or O+ blood.
If the mother is A+, then the only way for the child to be O- is for the father to be O-.

It takes two genes for each trait, one from each parent.It is possible for the parents to each be heterozygous on the trait, that is, the mother AO and the father OO, giving a chance for OO for the child. Likewise rh factor takes 2 and both could carry half of rh factor which would make them positive.To get a negative you need 2 negatives, to show positive, only 1 positive.

I'm not sure but according to the chart it should have been an A.. Only when both parents were an O did the child have an O. According to this site I found.
I'd ask your doctor to be sure before you get too stressed about it. Good luck.

No that is not possible..The baby should either have A+ or O+ like one of its parents..

i think no..
coz the blood group of the baby will match to one of his parents..

yes it's possible because rh- gene is recessive but it's very unlikely...
