Yes, exactly. Thank you for pointing that out. However, the HUGO man
should have two separate alleles. I would expect that this is quite a
conservative/stable marker with not much variation, but it might be
interesting from the aspect of observing recombinational reductions of

Ken N. wouldn't agree with you, I guess...
I mainly try to get a better insight in duplicated markers in general.
Advanced methods in typing duplicated markers help us in making allele
calls correctly. I always whish to be able to distinguish two distinct
alleles with the same length from a deletion of one of the two alleles.
