Why there is no effect when a rhesus negative man marries a rhesus positive woman?
Wiki User
∙ 11y ago
In the cross between an Rh positive man and and Rh negative woman, the following possibilities will result:
- The child is Rh negative
- The child is Rh positive
In the former case, there is no issue since the Rh of both the child and the mother are alike. There will be no problems during the gestation period.
The the latter case however, when the child is Rh positive, there is a good chance the mothers immune system will begin producing antibodies against the child's red cells. Keep in mind there is intermixing of fetal and maternal blood at the placenta. This situation is not a big concern either. The mother is given immunosuppressant and the child survives.
If the woman gets pregnant for the second time with an Rh positive child, the mothers immune system will not fight against the fetus and result in hemolytic disease of the new born. Erythroblastosis fetalis is an example of this.

∙ 14y agoCertainly. There is no problem with the marriage. However, when having children, a woman could be exposed to the rh+ antigen. On her second pregnancy, if she again carries a child with the rh+ antigen, she will mount an immune response against the fetus unless she receives a treatment with RhoGam. This is a very common and safe treatment in the United States and many parts of the world. This eliminates the risk of danger to the mother or fetus.

My grandmother has - blood, my grandfather + blood and their children both have + blood.

What blood types would your parents have to be to have a child with A positive blood type?
Discounting rare but possible mutations the following holds true. Parents blood groups A and A, A and B, A and O, B and B, B and O, O and O can produce type O blood in their children. The rhesus factor (Rhesus positive/rhesus negative) depends on the rhesus pairing in the parents as follows: Father rhesus positive, mother rhesus positive or rhesus negative = rhesus positive or rhesus negative Father rhesus negative, mother rhesus positive = rhesus positive or rhesus negative Father rhesus negative, mother rhesus negative = rhesus negative Example: A rhesus positive father and rhesus positive mother of blood type A and O respectively could produce an O positive child, as could a rhesus positive father and rhesus negative mother both of blood group O.

Can blood be either B positive or negative?
Not exactly. Human blood may have positive (ca. 80%) or negative (remaining 20%) Rhesus factor. It means that that a substance known as Rhesus factor is either found or not in a human blood test. Transfusion of "positive" blood to a "negative" recipient may result in very negative consequences (but not vise versa) . A problem known as Rhesus conflict may arise when a Rhesus-negative woman is pregnant with a Rhesus-positive baby.The name Rhesus factor comes from Rhesus monkey in which it was first found.
What does plus and - stand for in blood group?
positive and negative stands for either Rhesus Positive or Rhesus negative which means that a persons Red blood cells (RBC) either have D antigens on their cell surface membranes or not. a person who is Rhesus negative will have D Antibodies in the blood plasma and can only be given Rhesus negative blood types in a blood transfusion. Rhesus positive blood types can be given either D+ or D- in a blood transfusion as they have no D antibodies in their blood plasma. hope this helps
What 3 kinds of blood?
1) Rhesus positive 2) Rhesus negative 3) A 4) B 5) AB 6) O
What are the benefits of o negative blood?
If you are a blood donor your blood can be given to anyone. Everyone who is O negative is OO negative, by father, husband and both my sons are all O negative. If you are a rhesus negative woman married to a rhesus positive man you may need to have Anti-D while pregnant and after delivery to prevent your blood becoming sensitised and affecting a Rhesus positive baby More elaborate answer on pregnancy in rhesus negative women: If you are a rhesus negative woman pregnant by a rhesus positive partner you WILL (typically only after the first pregnancy, but, it's suggested with any pregnancy of a Rh- woman) need a RhoGAM (Anti-D) injection in early pregnancy to protect the embryo from being miscarried from an attack by your immune system and again during or immediately after delivery to stop the fetal blood (which most likely will be positive) from mixing with your blood preventing your death. Negative can successfully mix with positive, but, positive will kill a negative.
Can the baby of an O rhesus positive and a A rhesus negative parent be A rhesus positive?
no cause a positive and negative make a negative unless the positive has a really strong blood line
B Rhesus Positive Anti-P1 negative?
B rhesus positive anti-P1 negative
If two parents have A-negative and O-negative bloodtypes is it possible for their child to be A-positive?
No. Two rhesus-negative parents cannot have a rhesus-positive child.
