YFull analysis of kit 447170/YF05542, Sweden BigY BAM file, and Francalacci et al Sardinian samples ERS256808, combined with results from scientific studies (EB-35147 Alban2 and ERR1025614), allowed to discover a new Z1297 subclade: J2b2-Y23094,B440 – parallel (brother) to Z1295:
According to YFull YTree v.4.09, J2b2-Z1297 diversified ca. 4200 ybp and TMRCA of J2b2-Y23094 is ca. 3200 ybp. Predicted Y23094 Y-STR haplotypes from J-M241 Project at FTDNA are diverse and range from Balkans, Italy, Central and NW Europe. In addition to Genetic Distance analysis, DYS607=13 appears to be a good predictor for potential Y23094 haplotypes.
The following SNPs currently define this subclade: Y23094, Y23095, Y23096, Y23097, Y23098, B440.
