Children who inherit an A-O combination will be type A, but, remember, they could still pass that O gene off to their children. As a result, their child could wind up as type O if the other parent passes them an O-type gene, too.
Can O+ and O have a baby?
That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type. Each of their kids will also have a 3 in 8 chance of having A+, a 3 in 8 chance of being O+, and a 1 in 8 chance for being A-. An A+ parent and an O+ parent can definitely have an O- child.
