I1a telling markers
Per Ken N. - If you have 67 markers you have DYS511. Within I1a it serves the same purpose as DYS462 ninety-nine percent of the time
DYS462 =12 goes with DYS511 = 9
DYS462 = 13 goes with DYS511 = 10
This is only true in I1a. Also if you check your DYS455, if it is 8 you are I1a, 99.9 percent confidence. If you are 11 at DYS455, you are not I1a; basically total confidence based on the thousands of haplotypes seen to date. DYS388=14 is another very good indicator for I1a.
For those interested in the technical details, kindly provided by Nordtvedt, Norse I1a (14/23/14-14) and ultraNorse I1a (14/23/14-15) is dominantly DYS 462 = 13; while AngloSaxon I1a (14/22) is dominantly DYS 462 = 12. DYS 462 mutates extremely slowly and thus results are strong modals for research, Nordtvedt said.
