Yes, the firstborn baby can be Rh negative if both parents carry the Rh-negative gene. The Rh factor is inherited from the parents, and if the mother is Rh negative and the father is also Rh negative, their child will be Rh negative. However, if the mother is Rh positive and the father is Rh negative, the child can either be Rh positive or Rh negative depending on the specific alleles inherited.

Why do rh positive parents have an rh negative baby?
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.
What type blood does a negative male and o positive female make?
There's not enough information to give the probable blood groups since no blood group was given for the male. However, an rh negative male and an rh positive female could produce either an rh negative baby or an rh positive baby. The male is definitely homozygous recessive for rh factor, but the female could be homozygous dominant for rh factor, in which case the baby would be heterozygous for rh factor and it would be rh positive. However, if the female is heterozygous for rh factor, there is a 50% chance the baby would be rh positive (heterozygous) and a 50% change the baby would be rh negative (homozygous recessive).
Rh positive mother a positive baby?
If a person has the Rh factor, then they are positive. If they don't have the Rh factor, they are negative. The Rh factor is dominant, so a mother with it would have an Rh positive baby even if the father is negative for the Rh factor.
What are the possible blood types the baby could have if the mother is type O-positive and the father has the rh-negative blood type?
The baby's blood type would depend on the specific genotype of both parents. With a mother who is O-positive and a father who is Rh-negative, the baby could potentially have blood types A-negative, B-negative, AB-negative, or O-negative.
Can an Rh negative father and an Rh negative mother have an Rh negative baby?
yes

Can baby be negative if mom is positive and dad negative?
It takes two rh negative parents to produce an rh negative baby.
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 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.
How does Rh factor affect a fetus?
When a mother is Rh negative and her baby is Rh positive, she may develop antibodies to the baby's blood that will cause it to hemolyze

Can a baby have B negative blood if the mother is B positive and the father is A negative?
Either. We know the mother is homozygous recessive rh- rh- for rh factor, so she can only pass on an rh negative allele to a child. However, if the father is heterozygous rh+ rh- for rh factor, he could pass on one of those two alleles to a child. If he passes on the rh+ (dominant) allele, the baby would be rh positive. If he passes on the rh- allele, the baby would be rh negative.
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.
Do you need to get a shot for your RH factor at every pregnancy?
Yes because if you are RH negative and your baby is positive your body will attack the baby.
Rh positive mother a positive baby?
If a person has the Rh factor, then they are positive. If they don't have the Rh factor, they are negative. The Rh factor is dominant, so a mother with it would have an Rh positive baby even if the father is negative for the Rh factor.
If the mother has Rh positive and the father Rh negative are there problems for the baby?
Being Rh Negative implies that you do not have the Rh antibodies in your blood and the genes that are responsible for the formation of the antibodies. If both the Mother and the Father is negative and do not have the genes the baby can only be negative.
