Linkage disequilibrium

Linkage disequilibrium

(Science: genetics) The occurrence of some genes together, more often than would be expected. Thus, in the HLA system of histocompatibility antigens, HLA A1 is commonly associated with B8 and DR3 and A2 with B7 and DR2, presumably because the combination confers some selective advantage.

Re: Linkage equilibrium vs. Linkage disequilibrium?

Is this not a commonly asked question? I've read equilibrium vs. disequilibrium in my book and it just doesn't make sense to me at all. Has anyone heard of this expression?
