Yes. The positive or negative refers to the presence or absence of an antigen in the Rh system called the D antigen. A person who is positive for D can have one gene for it (a heterozygous state) or two D genes (a homozygous state).
Two heterozygotes could have a D positive or negative child.

Can a b positive and a positive have a b negative child?
No. If both parents are positive, the child will be positive. If both parents are negative, the child will be negative. Parents who are negative and positive can have children who are either positive or negative. '+' + '+' = '+' '-' + '-' = '-' '+' + '-' = '-' or '+'
If both parents are A positive what usually will the child have?
A or O positive or negative
If both parents of a child is posititive can the child be negative?
yes because you either get your parent's traits, the opposite traits, or a little of both but because both parents are positive the child could be positive OR negative
Can O negative parents have an O positive child?
If they are both O negative, no, the child will be O negative.
Can parents that are both a negative have an ab positive child?
No. If both parents are A negative the child can only be A negative or O negative. If the child is AB positive at least one parent must have type B or AB blood and at least one must be RH positive.
Can 2 Rh parents have a Rh- child?
No, it can't happen. if one of the parents or both are +, the child will be Positive. I don't know if 2 negatives can have a positive. But i do know that if one of the parents is positive and the other is negative, you can have a either a positive or negative child. (I have twins, one is negative and the other is positive.)
Can o positive and a positive parents have o negative child?
Yes. Since the Rh factor is recessive if both parents have a copy of the gene they can have an Rh negative child.
Can a child have a negative blood types if the parents are both a positive?
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 2 A positive parents have an O negative child?
No. O and Rh negative are both recessive traits--both alleles must be that trait before it expresses. The term for an A positive child from two O negative parents is "grounds for divorce."
If both parents are A positive can a child have negative blood?
Yes. If both parents have the recessive gene for Rh negative, a child of theirs could have Rh negative blood. I have two daughters who are Aneg, and both of us are A+.
If both parents have positive blood type will the child have a positive?
Probably, because it only takes one positive gene to have positive type blood. But if the positive parents each have one positive and one negative gene, there is a 25% chance their child will be negative.
Can a A positive blood type mother give birth to Rh negative daughter?
Can a child with RH neg blood come from parents that are A positive and A negative
