Are there any other blood types?
Answer:
When one talks of blood 'types', one is actually referring to the antigens on the red blood cell surface. (An antigen is a molecule, or part of one, that the immune system can target.)
There are two systems of antigens that typically cause the biggest immune reaction - the ABO group and the Rhesus group. Most blood types are reported only with reference to the two major 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, just because those two groups cause the biggest reaction (and thus are the most dangerous in a blood transfusion), it doesn't mean that these are the only types of antigens on the red blood cell surface. In fact, there are at least 30 commnly occuring antigens and hundreds of rare antigens. (Options like 'kell' and 'duffy' are among these.)
However most of these are weak and therefore of importance 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 list of the semi-common ones.

One last foot note: the 'bombay' in your question is not actually an alternative to the ABO system. Rather, the Bombay phenotype is a weird quirk of that system. If you're interested, you can go here: http://www.madsci.org/posts/archives/jan...
Hope that helps!
Thats it I think
ONLY ...
A
B
AB
O
Rhesus factor of + or - for each
there are actually O+ A+ B+ AB+ O− A− B− AB−
negative and positive of same ones listed
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 very rare ABO. there 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 matter, but if you have to deal with somebody who's had a lot of transfusions, they do begin to appear like mad.
