Question

What are the posible blood groups of child having one parent A+ & other A-?

Answer 1

The baby can be:

A+

A- (if the A+ parent has a recessive Rh- gene)

O+ (if both parents have a recessive O gene)

O- (if both parents have a recessive O gene and the A+ parent has a recessive Rh- gene)

Answer 2

I"m going to say that the child would be blood type A with a 3/4 chance of being RH positive, 1/4 chance RH negative.

Answer 3

They will either be - or +, but more likely + because - is a recessive factor. If however the baby is + you may need a shot so that your body doesnt try to build up antibodies to fight off the baby because it finds the + factor. I had to get a shot because I was - and my baby was +.

Answer 4

A child with two "A" parents can be either "A" or "O" I'm not sure about the +/- part though.
