I used http://www.Biology.Arizona.edu/Human_Bio/problem_sets/blood_types/btcalcA_popup.html (one the side where is says possible blood types for a parent) so the father has to be A+, B+, AB+ or O+ If you are AB- and your twins are A+ then their father would be either A+ or O+. The father could be A+, B+, AB+, or O+. The Rh+ must come from the father. The twins have blood type A, which could be either AA or AO. If the father is B+, he must be the BO version rather than BB.
Here are charts showing how, with the mother across the top with blood type AB, and the father down the left side. Father of type A, specifically AO:
___A__B
A | AA AB
O | AO BO
50% chance of type A, 25% chance of AB, and 25% chance of B.
Father of type A, specifically AA:
___A__B
A | AA AB
A | AA AB
50% chance of type A, 50% chance of AB
Father of type B, specifically BO:
___A__B
B | AB BB
O | AO BO
25% chance of type A, 25% chance of AB, and 50% chance of B. Father of type AB:
___A__B
A | AA AB
B | AB BB
25% chance of type A, 50% chance of AB, and 25% chance of B. Father of type O:
___A__B
O | AO BO
O | AO BO
50% chance of type A, 50% chance of B.

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 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.

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 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.
What 3 kinds of blood?
1) Rhesus positive 2) Rhesus negative 3) A 4) B 5) AB 6) O
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
What is the universal recipient in blood transfusions?
AB positive; a person with rhesus-negative blood can have an adverse reaction if given rhesus-positive blood.

What is the difference between negative and positive blood type A?
The Rhesus factor, also known as the Rh factor, is an antigen that exists on the surface of red blood cells. People who have the Rhesus factor are considered to have a positive blood type. Those who don't have the antigen are considered to have a negative blood type.
What blood type will the child be with parents blood type o negative mother and father 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 blood type a negative?
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.

Can a siblings with the same parents have differing RH factors?
I have a rhesus negative blood group and my sister has rhesus posotive. Does this mean we have different fathers
What is the different rhesus groups?
if you are talking about blood then I think it's positive and negative.
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.
