Each person carries two bits of rh imformation, called alleles, and each can be positive or negative.
A person is rh+ if they have at least one positive allele. Only if both their alleles are negative are they considered as rh-.
When two parents have a baby, they each pass one allele on. So if both parent has one positive and one negative allele, and both passed on their negative allele to their baby, then the baby would be rh negative.
The chances of two rh positive parents having a rh negative baby are about 18%.

Can a O negative parent and an RH O negative parent make a positive baby?
No, if both parents are O negative (meaning they do not have the Rh antigen), they cannot have a Rh positive baby. RH positive blood type requires the presence of the Rh antigen when processing blood types.
If both parents are rhesus positive can they have a negative baby?
Yes, it is possible for two Rh-positive parents to have a Rh-negative child if both parents are carriers of the Rh-negative allele. This means that both parents have a recessive Rh-negative gene that they can pass on to their child.
What type blood does a negative male and o positive female make?
A negative male and O positive female can have children with either A negative, B negative, AB negative, or O negative blood type. A negative is recessive, so both parents must carry the gene in order for their child to have a negative blood type.
Can a child born with rh negative blood type be the offspring of an o positive father?
Yes, a child born with Rh negative blood type can be the offspring of an O positive father if the mother is also Rh negative, as the Rh factor is determined by both parents' blood types. If the mother is Rh positive, the child may inherit the Rh negative trait from the mother and be Rh negative.
What are parents blood group with their first baby is of blood group o negative?
If the first baby has blood group O negative, it means that both parents must have passed on an O gene and a negative Rh factor gene to the baby. Therefore, the parents could have blood groups A, B, AB, or O with negative Rh factor.
Mother is o positive and father is o positive Does this mean baby will be o positive?
No. There's a small chance the baby will be O negative--if both parents have an Rh negative (recessive) allele, and the baby inherits this allele from both parents, the baby would be Rh negative. But if the baby inherits the Rh positive allele from either parent, the baby will be Rh positive.
Can baby be negative if mom is positive and dad negative?
It takes two rh negative parents to produce an rh negative baby.
If the parents are Rh positive could they produce an Rh negative child or just Rh positive offspring?
We are looking for the possible Rh blood types of a baby.Parental information:Mother Rh pos -- can be (++) or (+-) = contributes (+) or (-) geneFather Rh pos -- can be (++) or (+-) = contributes (+) or (-) geneBaby receives one gene from each parent: Baby is Rh (++) = Rh posBaby is Rh (+-) = Rh posBaby is Rh (--) = Rh negTherefore, depending on the exact genetics of the parents, the baby may be Rh positive or negative.
Can a O negative parent and an RH O negative parent make a positive baby?
No, if both parents are O negative (meaning they do not have the Rh antigen), they cannot have a Rh positive baby. RH positive blood type requires the presence of the Rh antigen when processing blood types.
Can two parents with A positive blood have an Rh A negative baby?
not chance,but rarely can be.
Can a baby be born with positive blood if both parents are negative?
No. If both parents are Rh negative, they are homozygous recessive for the Rh factor and can only pass on recessive alleles to their children, and a positive Rh factor is a dominant trait.
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
If both parents are rhesus positive can they have a negative baby?
Yes, it is possible for two Rh-positive parents to have a Rh-negative child if both parents are carriers of the Rh-negative allele. This means that both parents have a recessive Rh-negative gene that they can pass on to their child.
Can a rh positive father have a rhs negative baby?
Yes, it is possible. There are two genetic alleles that together determine whether a person is Rh positive or negative. It is the combination of these alleles within the parents that determine the child's Rh status. In this case, both mother and father are positive so their alleles can only be ++ or +-. The possible combinations are determined by taking one allele from one parent and combining it with an allele of the other until all combinations are made. Positive is the dominant allele so combinations of ++ and +- are considered Rh positive whereas -- combinations are negative. The possible combinations are: ++ which would be an Rh positive baby +- which would be an Rh positive baby -- which would be an Rh negative baby So yes, it is possible.
Can both of the parents be RH Neg and still have a healthy child?
Yes. You will occasionally have problems if the mother is Rh negative and the father is Rh positive; if the baby is Rh positive, there is a possibility for complications if the baby's blood poisons the mother. This is pretty rare these days.
Can parents have negative and positive Rh children?
CAN children hae positive and negative RH factor blood types
Can two A positive parents have an Rh- baby?
No, two A positive parents cannot have an Rh- baby because the Rh factor is inherited. A positive blood type is always Rh positive, so both parents must have at least one Rh positive allele to pass on to their child.
