Hello, I have several lines that are doing DNA testing to determine linage paths. And, although I have heard that the tests are 'relatively' inexpensive (when compared to what they used to cost! Still, a major expense for my genealogy budget), it would be wonderful if the different DNA projects could use the same test results. So, my questions are: Can my different lines share the results? Is there an added expense to do that? In other words, do the results have to come from the lab itself, or can you send copies of the report and still be part of the study? If they are required to come from the lab, does the lab charge for each report sent? Thanks for your input, Cec Barton My Line: Wm(sn) & Mary > Elisha & Martha > Wm & Sarah > Elisha & Martha > James David & Mary > Sarah Pace & Ben Bolter > Rose & Benj.

yDNA results reflect only the paternal line (male to male to male, etc) and so would be relevant to only that line. There is a danger in assuming that the Y profile of a cousin is the same as your own, since the risk of a non-paternal event increases with the number of births that separate you and the cousin. Mutations do occur in the Y chromosome markers, so multiple samples may be needed in order to predict the Y profile of a distant male ancestor. The mutations are random events and yDNA usage in genetic genealogy becomes an exercise in statistical probabilities. The more data points (yDNA samples) that you have, the more reliable the prediction. I had a 26 marker test done on my Y last spring by Relative Genetics for $99. To get that price, I sent in a DNA sample to Sorenson Molecular Genealogy Foundation, along with a 4 generation family tree. In return, they sent me a $50 coupon for either the yDNA or mtDNA (female line) test. But FTDNA seems to have a monopoly on surname projects, and I haven't been able to persuade the Anderson project to use my results, though 21 of my Relative Genetics markers match the FTDNA markers. No other Anderson cousins in my known line have had the yDNA analysis done, so I need several more samples before I can predict the Y profile of Jonathan Anderson who died in Marengo Co, AL, in 1836. It was probably very like my own, and maybe exactly like mine. Unless Grandma got too friendly with the preacher way back then. You never know - even in the best of families . . . .
