In search of the Pre- and Post-Neolithic Genetic Substrates in Iberia: Evidence from Y-Chromosome in Pyrenean Populations
From the paper:
However comparing the average STR variances of the R1b1b2c (0.243), R1b1b2d (0.207) and I2a2 (0.278) lineages considered in this study and given the replicated estimates pointing to a Mesolithic time frame for the origin, diversification and diffusion of the I2a2 clade (Rootsi et al. 2004), the temporal interpretation here provided for R1b1b2c seems reliable.R1b1b2c==>R1b-M153 (n=19, var=0.243)
Calculated using DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439.R1b1b2d==>R1b-SRY2627 (n=30, var=0.207)
Calculated using DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, GATA H4.I2a2==>I-M26 (n=13, var=0.278)
Calculated using DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, GATA H4.
Thank you, JeanL.
Just a clarification for everyone, these numbers from the study are reflective of the study and the regions within its scope. It is not a Pan-European study.
As far as R1b-M153, that region is the only place where its been found other than perhaps one haplotype in the Old Norway project. SRY2627, is more widespread than M153 by a longshot with people in the British Isles, Benelux, Scandinavia, Germany as well as all over Spain and France.
If you compare M153 with SRY2627 (from everywhere), at least with long haplotypes, SRY2627, is quite a bit older. The M153 that entered the Basque or pre-Basque population may have come in at a late point in time after SRY2627 had been around as it (SRY2627) scattered all over Western Europe.
What do you make of the fact from the study that I-M26 is 14-34% more diverse than the SRY2627 or M153 in this study?
I'm a bit nervous of deriving too much from just 10 STRs.
