Are in that any other blood types?
When one negotiations of blood 'types', one is actually referring to the antigens on the red blood cell surface. (An antigen is a molecule, or slice of one, that the immune system can target.)
There are two systems of antigens that typically cause the biggest immune sensitivity - the ABO group and the Rhesus group. Most blood types are reported only near reference to the two central systems. Thus, for the ABO group, you can be A, B, AB, or O; and for the Rhesus group, you can be positive or negative. (E.g. A+)
However, simply because those two groups cause the biggest antipathy (and thus are the most dangerous contained by a blood transfusion), it doesn't mean that these are the single types of antigens on the red blood cell surface. In fact, near are at least 30 commnly occuring antigens and hundreds of occasional antigens. (Options like 'kell' and 'duffy' are among these.)
However most of these are pale and therefore of hurry principally for studying the inheritance of genes to establish parentage.
Check out the following web site for a more detailed look at other blood types, including a document of the semi-common ones.
One last foot entry: the 'bombay' in your grill is not actually an alternative to the ABO system. Rather, the Bombay phenotype is a chance quirk of that system. If you're interested, you can go here: http://www.madsci.org/posts/archives/jan...
Hope that help!
Thats it I think
Rhesus factor of + or - for respectively
there are certainly O+ A+ B+ AB+ O- A- B- AB-
negative and positive of same ones down
Kell, Duffy, McLeod, Rh, Dombrock, and practically 20 more known blood types.
That's it... red.
BLOOD GROUP ARE DISCOVERED BY LANDSTEINER.
THERE ARE FOUR BLOOD GROUPS-A,B,AB,O
O - BLOOD DONOR
AB CAN DONATE BLOOD TO AB
A CAN DONATE TO A AND AB
BLOOD GROUP - ANTIGEN
B - B
A - A
AB - A AND B
O - NONE
there's A, B, AB, O, and one unbelievably rare ABO. in attendance are differences between the types ((the Rh factor in some of them.))
The ABO grouping, Rh types, Du, and a plethora of minor ones that usually don't situation, but if you have to accord with somebody who's have a lot of transfusions, they do get going to appear like cracked.
