Helen, Chromo2 is a similar technology to Geno 2.0 but more uptodate and with new detailed structure under your current terminal SNP which is called M222. It covers a superset of the other marker you mention DF85 but is more expensive. It is not possible to reliably predict whether you are likely DF85 positive and if you are you would then as a minimum need to test DF97 too. There is another marker on Chromo2 which is likely equivalent to DF97 although we don't have any test results to confirm that yet. So its USD39 (+ maybe another USD39) v USD199 to be sure, or give you more details if you are DF85 -ve. Most people overall have been DF85-ve and are now having to order Chromo2 anyway so are paying twice. I've had a look at your markers and all I can say is you are within the range where there is somewhat of a chance you are DF85+ but you are on the edge of the range. There is a diagram of test results so far at: http://www.kennedydna.com/M222.pdf Chromo2 is sold by ScotlandsDNA who also trade as IrelandsDNA. This is the direct button to place an order: http://www.irelandsdna.com/mydna/basket/add/6 Personally I would go straight to Chromo2. But no-one knows in advance which route will be most economical for you. Your question about another Murphy line is irrelevant. This is a Y chromosome test and the Y doesn't recombine with other genetic lines, it is a pure paternal father to son test all the way back.

What is the USA cost of Chromo2? What is it and where do you get it?? I myself have done my own Geno2 with National Geographic... is it the same thing??? > > I am having to finance these tests, so I am cautious what I have to order, would it be just as good to order DF85 at $39.00 ? > > My next question is his Y-DNA never quite matches exactly other Murphy's markers... off usually 1 marker or so. I am wondering if it is because he also has another Murphy 2nd great grandfather also born in Ireland. Could this throw his markers off a bit??
