Quick question guys.
I've tested as being R-BY20474 positive via FGC Elite 2.1 and also at YSEQ. I've also tested as being positive for BY20464 (FGC72622) at FGC.
FTDNA has this SNP listed in their tree as being under ZZ37 as does Alex's P312 tree, with the routes being P312>ZZ37>BY20464>BY20474 at FTDNA and, following my submitting my data, P312>Z40481>ZZ37>FGC72599(BY20464)>BY20474(FGC72622) on Alex's tree. FTDNA does not list Z40481 in their tree (presumably because it is an STR and not and SNP).
FTDNA list ZZ37 and ZZ38 as being separate (and have confirmed that I am ZZ38- via the P312 SNP pack) and Alex's tree views them as being synonymous (but does indicate that their exact position is ambiguous). YSEQ won't test ZZ37 or ZZ38 due to them being in the unstable DYZ19 region. The Eupedia tree also gives a progression of P312>Z40481>ZZ37 but doesn't (as yet) list BY20464 or BY20474 in the tree.
My confusion comes with the inclusion of the Z40481 STR in SNP trees and the progression to ZZ37. I've tested negative for Z40481 at YSEQ and can't work out how I could then be positive for SNP's downstream of it?
