Yes!

Parents have two genes for pos/neg blood type, and only one of them needs to be positive for the parent to have positive blood type. Most positive-blooded people have one positive gene and one negative gene. If both positive parents pass on their negative gene, they can have a child with a negative blood type.

Can two negative blood parents have an rh positive blood type child?

No. The negative blood trait is a recessive trait. Two negative parents only carry the recessive gene and cannot pass on the dominant positive gene. At least one parents must be positive in order to have a positive child. This is not like math where two negatives multiplied together equals a positive. IN this case, two positives can have negative or positive children depending on the parents phenotypes. two negative parents can only have a negative child.

If one parent is A negative and the other one is A positive what blood type would the child have?

The most likely blood type for the child is A positive - but A negative, O positive and O negative are also possible depending on the genotypes of the parents. If both parents are heterozygous AO, then the child could have either A or O type blood. If either parent is homozygous, AA, then the child must have blood type A. If the parent with positive blood is heterozygous, Dd (+-), then the child could have either positive or negative type blood. If they are homozygous, DD (++), then the child must have positive type blood.


Can parents with b positive and o positive blood have a child with O negative blood?
