Why there is no effect when a rhesus negative man marries a rhesus positive woman?
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.

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 3 kinds of blood?

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
Can o negative boy marry with b positive girl?
Yes, of course! Depending on the girl's underlying genetics the children will be either blood type 0 or B, rhesus factor positive or (rarely) 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.

What blood type will the child be with parents blood type O positive father and mother O positive?
The baby can only be an O Blood Group as both parents can only be carrying 'O' type genes. The baby would have a 75% chance of being an O positive and a 25% chance of being an O negative. This is because the mother can only pass on a Rhesus negative gene but the father might either have two Rhesus positive genes or one Rhesus positive and one Rhesus negative. If the first is true the child will only be O positive, if the second is true it could be O positive or O negative depending on which gene the father passes.
How common is a negative blood?
No, only 7% of the world has O negative blood type.We couldn't say our blood type a negative without testing.It has been found that the most common blood types are the Rhesus factor positive or all the positive blood types like A+, B+, AB+ and O+. When compared with their respective negative counterparts, the percentage of the positive blood types is more than that of the negative ones. That is, nearly 85% of the world population have Rhesus positive blood type, while only a mere 15% have Rhesus negative blood type.
