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 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
Is o negative is a universal blood donor?
Yes, as both 'O' and rhesus negative are recessive genes.
Why is blood group O not always a universal donor?
The classic blood typing into groups A, B, AB or O is only one way to divide up the population. Also whether you are rhesus negative or positive can play a big part. If you are type O but rhesus positive, your blood cannot be given to someone type O but rhesus negative or their immune system will react to the rhesus part of the donated blood.
What blood group is used for transfusion to blue babies?
O Rhesus negative
What percentage of donors have O rhesus negative blood?
In the U.S., approximately 6.5% of individuals have the O- blood type. (By comparison, about 38% have the O+ blood type.)
How many blood types are there how blood type is inherited?
To the second question the answer, in short, is YES; To answer the first question, there are four logical blood types: A, B, AB, and O. Then there is the Rhesus factor: either positive or negative. So there are actually eight types of blood a human can have: one of the above types with a negative Rhesus factor or with a positive Rhesus factor. Rhesus factor is a factor which compares human blood to a Rhesus monkey's blood. A negative result means your blood is not comparable to a Rhesus monkey. Blood types are inherited from your parents. If one parent has type A+, and the other has a B-, your blood type can either come out as A, + or -, or B, + or -, or the rare AB, + or - but not O. While type O negative is the universal donor, type AB positive is a universal recipient.
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.
What is 3 kinds of blood?
1) Rhesus positive 2) Rhesus negative 3) A 4) B 5) AB 6) O
What 3 kinds of blood?
1) Rhesus positive 2) Rhesus negative 3) A 4) B 5) AB 6) O
What are four phenotypes of human blood?
The most commonly referred to are A, B, AB and O. Others include rhesus-positive and rhesus-negative.
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.
