I've just received this notice from FTDNA--will the matching system be sufficient to eliminate the painstaking comparisons that have been necessary to this point to identify new downstream SNPs? If so, then I will ask whether any L1275s or L1274s are interested in taking advantage of the sale on Big-Y. I Lindsey PS I wonder how long "phased" will be. "Big Y matching is coming! Over the course of the next two weeks we will begin a phased release of Big Y matching so you can directly compare your comprehensive Y-DNA results to those of other Big Y test takers. The key to identifying all new SNPs and subclades is finally here!"
