Blood typing situations
« on: 30/01/2006 01:30:35 »
ABO antigens are sugars attached to a membrane protein.  Type A cells have one type of sugar, Type B a slightly different type, and Type O lacks the sugar.  Some people have a genetic condition where they do not make the membrane protein. If a person carries the allele for Type A but does not make the membrane protein, what blood type would a standard blood test say they are? Why?

A standard blood test, I'm pretty sure, would involve antibodies for the A and B antigens (sugars) so if the individual doesn't make the protein and therefore doesn't carry the antigens on the blood cells, a blood test will show them up as type O.

Not meaning to be rude, but this reads a bit like a homework assignment question that's been directly transcribed. Which isn't really the point, either of assignments or of this website.

If you've just come up with a question to which you want to know the answer, take that as a compliment, it's very well phrased and direct.
