Subject: [DNA] 21 for DYS 390 and other rare values
Date: Thu, 1 Aug 2002 03:51:39 EDT
I find Nancy Custer's remarks on the rarity of particular values very
interesting indeed, and now make use of her graphs at
http://www.contexo.info/YSTREuropeFrequencies.htm
to indicate "rare" numbers with a special sign in my tables of results for
the CARDEN DNA PROJECT, and find this very helpful in drawing conclusions.
For two subjects to share a rare value must be far more significant than
sharing any number of commonplace values.
She mentions that a value of 21 for DYS 390 has a frequency of only .0466.
I have two Cardens, both from Co Sligo, Ireland, with 21 for DYS 390. Does
anyone else have an occurrence of this very rare number?
