Trent, Here is a link to some information that is posted in the Forums about the numbers and what they mean. Keep in mind when reading this posting, that DYS is the same as Locus and the posting will make a lot more sense! http://forums.genealogy.fm/forums/index.php?topic=15.0 As always, Adrian -----Original Message----- From: catcoop@bellsouth.net [mailto:catcoop@bellsouth.net] Sent: Thursday, May 25, 2006 11:17 AM To: WILLIAMS-DNA-L@rootsweb.com Subject: Re: [Williams-DNA] RE: Y-DNA DYS VALUES Hi Trent, I can provide a very basic explanation, but someone else on the list could probably provide a more detailed, scientifically correct explanation. The DYS numbers (columns) are simply numbers assigned to identify the DNA markers tested on each person. The numbers in the rows and under each marker represent your specific values for each of the markers. For example, one person might have a value of 12 at DYS388 while another person might have 14 at DYS388. These values (12 and 14) represent the number of times a short pattern of nucleotide bases repeated in a row on your marker. If you took a 25-marker test and matched another test on 24/25 markers or 25/25 markers, then you would be considered a match within a genealogically relevant timeframe. Hope this helps!
