A slightly upstream snp discovered by the 1000 Genomes people has entered FTDNA catalog --- DF29. This should prove an interesting snp to test for by the surprisingly many generic I1xL22 folks who have turned up Z58- Z63- and presumably Z131- DF29 could divide this generic population into DF29+ and DF29- Also, several well established clades of I1xL22 have turned up Z58- Z63- Z131- Representatives of those clades should also test for DF29 to see if clade is derived or ancestral. An L22+ or two should test whether that division of I1 is ancestral or derived for DF29. 1000 Genomes suggests it will be derived. Ken
