Cheers Neil!

That explains things.  I guess I'll keep these in my database.

By coincidence, we were looking at this yesterday:

http://www.ensembl.org/Homo_sapiens/Info/Content?file=haplotypes.html

Basically, some regions of the genome are so polymorphic *and*
important, that a few alternative named haplotypes have been assembled.

I'd actually quite like to know where this is going under the influence
of the 1000 Genomes - is the *whole* genome going to get these
alternative haplotypes, or is there some other cunning plan to represent
relative and absolute positions?

Cheers
Neil
