What don't I understand? I have two new members, both tested at 12 markers only, whom I assigned to my Northwest Cluster. One has the identical haplotype as "Niall," and FTDNA awarded him the Niall green icon. Yet his suggested haplotype is R1b1. When I asked FTDNA why he was not suggested to be R1b1c7, I received this reply:
"Due to convergence, some 12 marker haplotypes who match the Niall of Nine Hostages are not also R1b1c7 so matching the Niall lineage on 12 markers does not automatically mean belonging to R1b1c7. The males who have had 12 markers tested and have received SNP tests are used in the comparison of 12 markers for the purposes of predicting the haplogroup for a sample. Not everyone who has tested in the SNP database has had the Deep SNP R1b1 performed on their sample and the R1b1s that are shown, now, outnumber the R1b1c7s. As this changes with more people testing the prediction will likely change to R1b1c7 on the personal pages and eventually in the chart."
OK, The other member, who came in through the Genographic project, does not have the green icon, is only an 11/12 match with Niall (he has 15 at 292 while Niall has 14), but is suggested to be R1b1c7. Wouldn't the convergence caveat also apply to him?
