Question

If a dad has a positive O blood type and the mom has a positive O blood type as well, the child will have an O positive blood type right?

And is it possible for the child to have an O negative blood type?

Answer 1

Either the child could have o positive or o negative. Or rH negative/positive.

Answer 2

Ok, umm whats rh negative/positive?

Answer 3

The mother's body may make antibodies to the Rh antigens in the baby's blood. This means the mother has become sensitized and her antibodies may cross the placenta and attack the baby's blood. Such an attack breaks down the fetus's red blood cells, creating anemia (a low number of red blood cells).
