Can a baby be born with blood group O if mother is blood group ARh negative?

The answer is no. If both parents have a positive Rh factor, the child will have a positive Rh factor. For example, my mother's blood type was O positive and my father's blood type was A negative. My blood type is 0 negative. I got my mother's blood type but my father's Rh factor. The negative Rh factor has to be passed from parent to child. If both parents had negative Rh factors the child in question would also have a negative Rh factor. The different types of blood, a,b,o,ab, and abo have no influence on the child having the negative Rh factor. Expecting mother's having the negative Rh factor need injections of Rhogam if the father of the child has a positive blood type. This is needed because the mother's body will attack the fetus if the baby has a positive blood type. The body doesn' recognize it and treats it as an invader. The baby can be born severly anemic or can even die. This will also effect pregnancies after that so I urge you to speak with your doctor regarding this issue. I hope I answered your question.

∙ 14y agoIt can affect their babies, mainly after the first baby. If the mother is Type O negative, and the first baby is positive, then there may be a danger to future positive babies because, during the first pregnancy, the mom's body may produce antigens to the positive blood type. This scenario may be why blood tests are taken when couples marry. A doctor should be consulted.

∙ 13y agoin your question you didn't mention what id the Rh type for both parents.
but anyway for a child to be
if father is Rh+ mother Rh+
kids will be all Rh+ and with low percentage reaches to 25% to have Rh- child
if father Rh- and Mother Rh-
all kids will be Rh-
and childrens will be type A or O .

∙ 11y agorH is not the blood type. Everyone is either rH negative or positive, and this is unrelated to the letter portion of the blood type. If both parents are O, baby will be O also. Parents' rH factors (+/-) will determine baby's rH separately.

Can father is A blood group and mother is B blood group and baby is male or female?
It depends. If the mother is heterozygous rh+ rh- for the rh blood type, then the baby could inherit an rh- allele from both parents, and then it would be rh negative.
Can a mother with a negative blood and father with o positive blood have b positive blood group baby?
No. For a person to be "O" blood type, they have a phenotype of O, which can only come about if they have a genotype of OO. If both mother and father are O's then they have no B that they can donate to the baby.
How does erythroblastosis fetalis develop?
It happens when the father is of a positive blood group (having Rhesus (Rh) factor) and mother of a negative blood group (devoid of Rh factor), the fetes' blood group will be of the positive type, i.e., having Rh factor as having Rh factor is a dominant trait and can mask the negative blood group. So, this creates problems for the kid as well as mother during pregnancy. Usually, the first pregnancy will not have much complications. But, the second pregnancy onwards, the antibodies present in the mother from the first pregnancy will be present and is harmful for the fetes.

What blood type will the offspring be if the Mother has A- blood and the father has O- blood?
the blood group of baby can be O,A,B or AB.
What blood type can a baby be if the father and mother are both type B positive?
The baby may be any of the following: * B positive * B negative * O positive * O negative
Can a o positive mom have a a negative baby?
Yes
Can Father O plus blood type have baby with O negative blood type?
It is possible. It depends on the blood group of the mother.
Can father is A blood group and mother is B blood group and baby is male or female?
It depends. If the mother is heterozygous rh+ rh- for the rh blood type, then the baby could inherit an rh- allele from both parents, and then it would be rh negative.
Can a mother have a positive and father have b positive can have baby with o positive blood group?
Yes, a mother with negative and a father with O positive can have a baby with B positive. If they do, the mother must have blood type B or AB.
Why does haemolytic disease of the newborn not occur in rhesus positive mothers with a rhesus negative baby?
HDN only occurs in rhesus negative women who have been sensitized by positive blood. Rhesus positive mother can have a rhesus negative baby. In rhesus positive group, they have the antigen Rh. When this antigen from baby enters mother's blood circulation, because of inutero bleed in pregnancy; mother's blood cells will react to the foreign antigen and produce antibodies which are harmful to the baby's blood cells when they cross the placenta and enter baby's blood stream. These antibodies will break baby's blood cells down causing haemolytic disease. Whereas in rhesus positive mother with negative baby, if baby's blood enters mother's circultaion it will not produce any antibodies as there are no antigens in Rh negative blood. And if mother's blood mixes with baby's blood in the womb, baby will not have the ability to produce antibodies as their immune system is not developed. So there is no chance for haemolytic disease.
Can a mother with b negative blood and a father with o negative blood make a baby with ab negative blood?
no
My blood group is O negative and my wife's B positive any problem for her pregnancy or for kids?
If mother is Rh positive there will be no problem. Problem can arise when mother is negative and baby positive.
What are parents blood group with their first baby is of blood group o negative?
a positive
Can I become a father because my blood group is A- and my wife's blood group is positive?
Yes, people with any blood group can have a child.Problems can occur if the mother is Rh negative, and the baby is Rh positive - because the antibodies of the mother may act as if allergic to the baby.There should be no problems with a Rh positive mother.
If the mother is O Negative and the father is B positive what blood group will the baby be?
I think more likely B, not sure though.
Can a man with blood group o positive be father to a baby with blood group o?
Yes, so long as the mother isn't O. The negative gene is recessive.
Your blood group is A- your wife's B plus is there any problem to conceive a baby?
No there will be no problem if mother's blood group is posotive and father's is negative as during pregnance if fetous is negative then when parturation occurs and if mothers blood is mixed with child blood then even there is no problem as both have -ve and in case if child have blood group +ve then even due to presence of -ve blood of mother it will not create any antibodyBut if the blood group of parents are reversed then there can be a problem
