BLOOD TYPES 🩸! why do we have different blood types?

There are four main blood types, which are determined by the presence or absence of specific antigens on the surface of red blood cells. Antigens are substances that can trigger an immune response, and in the case of blood types, they determine whether or not a person's immune system will accept or reject a particular type of blood.
The four main blood types are:
A - has A antigens on red blood cells
B - has B antigens on red blood cells
AB - has both A and B antigens on red blood cells
O - has neither A nor B antigens on red blood cells
In addition to the ABO blood group system, there is another antigen called the Rh factor. If a person has the Rh antigen, they are considered Rh-positive, and if they don't have it, they are considered Rh-negative.
So, a person's full blood type is typically written as A+, A-, B+, B-, AB+, AB-, O+, or O-, indicating both their ABO blood group and their Rh status.
Now, let's talk about how people get different blood types. Blood type is inherited from our parents, and it's determined by the genes we receive from them.
The gene that determines blood type is located on chromosome 9, and it has three different versions or alleles: A, B, and O. Each allele corresponds to a specific blood type.
Here's how it works:
- If a person inherits two copies of the A allele (one from each parent), they will have blood type A.
- If a person inherits two copies of the B allele, they will have blood type B.
- If a person inherits one A allele and one B allele, they will have blood type AB.
- If a person inherits two copies of the O allele, they will have blood type O.
The Rh factor is inherited separately from the ABO blood group, and it's also determined by a specific gene. If a person inherits the Rh gene from one or both parents, they will be Rh-positive. If they don't inherit the Rh gene from either parent, they will be Rh-negative.

im O from an O mom and an A dad...

[@mesterg6896]

You just inherited a recesive O from your dad. Im also an A- kid from 2 A+ parents

[@rusmayennisigit1039]

And why there is p type blood and rh_null and many other type blood?

[@saraturpin]

AB and O

Thank you

Wrong

[@SirAkivar]

You're missing A+ B+ and AB+ ?

[@travisstryder216]

me A+
