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.

Mother and father both rh positive what will baby be?

If both parents are Rh positive, the baby has about a 93% chance of being Rh positive as well. However, without knowing the genotype of the parents (i.e., whether they are homozygous or heterozygous for the Rh factor), it is not possible to predict the baby's Rh status with certainty.


IF a mother is HR negative and father is HR positive why is second pregnancy a problem?

If the mother is Rh negative and the father Rh positive there is a possibility that the unborn baby will be Rh positive as well. If the baby is Rh positive than the mother (who is Rh negative) has antibodies made for Rh positive substances which would include the baby. Basically the mothers body will attack the baby because it is not a match with her body. Commonly this is not as much of a problem with the first baby because the body does not build up the resistance to the first child but the second child will often run into complications because the body has built up antibodies against the second child's Rh positive blood. This is often called Rhesus disease or Rh disease.


Can the firstborn baby be Rh negative?

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 rh positive baby born to an rh negative mother is unaffected?

Because the mother's blood antibodies did not affect the child. However, if the mother is not treated with Rhogam after delivery the mother has a increased chance of creating antibodies that WILL affect her next baby in utero due to the rh incompatibility creating antibodies that could attack the fetus in utero. Make sure you receive RHOGAM! Hope this helps!


Can a child born with rh negative blood type be the offspring of an o positive father?

It depends on the genotype of the Rh+ parent. If that person is heterozygous, then yes there is a 50% chance of an Rh- baby.Father's Group (negative)Mother's Group (positive heterozygous)Rh +Rh -Rh -Rh +, Rh -Rh -, Rh -Rh -Rh +, Rh -Rh - Rh -http://www.bloodbook.com/inherited.htmlIf the positive parent is homozygous, the baby will be positive:Father's Group (negative)Mother's Group (positive homozygous)Rh +Rh +Rh -Rh +, Rh -Rh +, Rh -Rh -Rh +, Rh -Rh + Rh -

Can a father with a rh d positive and a mother with o rh positive produce a a rh negative baby?

yes if both are heterozygotes


Can a o negative blood type father have an a positive baby?

Yes, as long as the mother's blood group is Rh positive, the baby can be Rh positive. Only one parent need be Rh positive for this to occur.


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 a mother with A positive blood type and a father with O positive blood type produce a child with 0 negative?

Yes this depends on type off parent alleles Rh- ,,,,,,, alleles are (Rh-Rh-) Rh+ ,,,,,, alleles are (Rh+Rh+) or ( Rh+Rh-) if mother is (Rh-Rh-) and father is (Rh+Rh+ ) there is no chance to have Rh- baby, here all will be Positive if mother is A+ (Rh+Rh+) and father is O+(Rh+Rh+) also here there is no chance to have Rh- baby, and all will be Positive if mother is A+ ( Rh+Rh-) and father is O+( Rh+Rh-) the may have a negative baby but with very low percentage that reaches to 25%


How does having Rh positive mother and Rh positive father effect baby?

Generally the baby will also be Rh positive (depending on the parents' specific genotypes) - and thus be at less risk for erythroblastosis fetalis.


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.


Mother and father both rh positive what will baby be?

Could a Father with type b rh positive blood and mother with type o rh positive have a baby of blood type a positive?

No.


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


Why do you have to have a rh factor shot?

A Rh factor shot, also known as Rh immunoglobulin (RhIg), is administered to prevent Rh incompatibility during pregnancy. If an Rh-negative mother carries an Rh-positive baby, her immune system may produce antibodies against the baby's Rh-positive blood cells, leading to serious complications in future pregnancies. The shot helps prevent the mother's immune system from recognizing and attacking Rh-positive cells, ensuring both the mother’s and baby's health. It's typically given around the 28th week of pregnancy and after delivery if the baby is Rh-positive.

What happens if mother is rh positive and father is rh negative?

The rhogam shot is routinely given to mothers who are rh negative who may have rh positive babies. If you are rh positive there is no need to get the shot. However, if you are rh positive and get the shot it will not effect you or the baby.
