Blood type O cannot make blood type A unless another contributor's blood type is A because type O is recessive while A is dominant. For example, two type O's can only make blood type O. As for the rh plus or rh negative, since rh plus is dominant, type O- is capable of yielding a positive blood type if another contributor has a postive blood type. Simply adding rh plus will only change the blood type to O+.
In other words, O- plus rh plus cannot make blood type A+ unless another contributor has A themself.
Look up Punnett squares for blood types if this is just more confusing.
What else can I help you with?
Can parents both blood type B plus have a chlid with A- blood type?
No, it can't happen. none of the parents have the allele to make a kid with A blood type, and they can have Rh- child if both parent rh alleles are heterozygous.
Can a man with O rh plus and a woman with O rh plus have a child with O rh- blood?
Yes - it is possible. Firstly, if both parents have the blood type O, then the child must also have blood type O. Rh positive is dominant, so a person who is Rh + may be heterozygous (Rh+/Rh-). Both parents in this case would need to be heterozygous for the child to be Rh-.
What happen if you give RH- person RH plus blood if they have already been exposed to RH plus blood?
it will cause hypersensitization in RH- person
Can a baby be born with b rh- if parents are a rh plus and b rh plus?
Yes. Everyone carries a pair of genes for every trait (eyes, hair, even blood type). One is dominant and one is recessive.One of these parents likely a carried the B-Neg blood type on a recessive gene and it was expressed as a dominant trait in the baby.
What are the different types of Rh blood types?
There are two types of Rh blood type, a Rh + and a Rh -ve, they are useful in surgery so blood type can be matched. Especially in pregnancy it is beneficial for mother and child to have the same Rh blood type.
Are B and Rh one blood type or two different blood types?
B and Rh are two different blood type systems. The B blood type refers to the presence of the B antigen on red blood cells, while the Rh factor (Rh positive or Rh negative) refers to the presence or absence of the Rh antigen. This means someone could have blood type B+ or B-, indicating their blood type in both systems.
What antibodies and antigens are in type A plus blood?
Basically, Group A Rh (D) +ve blood type has antigen A and antibody B
Can you be O blood type and Rh negative"?
No, O blood type is always Rh positive.
What are Rh antigens?
They are a type of antigen that some people carry on their red blood cells. They are called "rhesus" because they were initially identified and studied on the red blood cells of rhesus monkeys, then were later also found in humans. If a person has Rh+ blood type they have this antigen, if a person has Rh- blood type they do not. They are important in blood transfusions in that a person with Rh+ blood type can receive either Rh+ or Rh- blood with no problems, but a person with Rh- blood type can only receive Rh- blood (Rh+ blood could kill him when antibodies from his immune system attack the rhesus antigen, causing massive blood clotting). They are important in pregnancy in that a woman with Rh- blood type has a much higher chance of miscarriage if her baby has Rh+ blood type. Note: there are roughly 30 different classes of blood type antigens, not just the familiar A, B, and Rh antigens. Most however are very rare.
Why can a person with rh- blood not receive rh plus blood?
The person with Rh- blood will begin to make antibodies against Rh+ upon exposure. This may not occur with the first transfusion - but it is still not recommended to give an Rh- person Rh+ blood.
What is Orlando Blooms blood type?
A(Rh-)
What blood type will a child have if the mother is an o plus and the father is an o?
A child with a parent with A positive and a parent with type O blood may be type A or type O. Without knowing the Rh factor of the second parent, it's not possible to say whether the child may have Rh negative blood.
