L-M317 STR marker likelihood tree focuing Alpine cluster

Comparison for the "Tyrolean-Rhaetic cluster" under L-M317 with DYS425=0: 2700 and E10323 had 67 markers, 199893 and 214163 had 37 Markers. All other kits have 67 or more Markers. The uncertainty if DYS425=0 is a common "unique event" is still unclear as seen by this comparison. One kit (97848) was forgotten to be included. The age of the common root L-M317 is still unclear and also for the more ancient root L-M20 no high consensus is reached: Wikipedia states "25,000-30,000 years BP", while some STR-comparison trees (M.Heinila) go down to 15,000 YBP. Based on this L-M317 has a range from to 16,000 to 8,500 YBP. <br>For better confidence an upgrade of 199893 to 67 Markers would be interesting: he shares one mutation with 2700, while 199893 and 214163 share two mutations. 214163, 199893 and 2700 should also test the SNP M317 for confirmation of the common root. For best possible confidence all four kits need 111 Markers. <br>For the future a common SNP of the "Tyrolean-Rhaetic cluster" should be searched: if no public Y-chromosome sequence will be available one or two of the kits should do a sequencing, if this gets cheap enough.
