Project Background
Project is for all haplotypes of J2 which are derived for SNPs L24/L25 (J2a4h).
Also if you are tested or estimated as J2 or J2a and carry DYS450=9, or DYS450=10, then you are likely a member of the J-L24 clade. If in addition you carry DYS445=10 (+/-1) or DYS445=6 (+/-1) then you are very likely a member of J-L24. These are just estimates. One cannot be 100% certain without actually testing the L24 & L25 SNPs. A Deep Clade J Extended test, for SNPs L24,L25,L26,& L27 is currently being offered by FTDNA (see your HaploTree page).
The SNP (mutation) rs35248080, assigned as L24, resides downstream of M410 (J2a), L26, and L27. The L26 and L27 SNPs replace the condition DYS413 <= 18-18 as SNPs are pretty much unique (statistically invariant) whereas Y-STRs in general are not.
The SNP rs34534058, assigned as L25, resides downstream of L24. L25*=L25(xL70), the root of this clade, represents the majority of the cluster with the modal characteristic defined by DYS450=9 and DYS445=10. Also included in L25* is another group having DYS445=6.
L70 is a new SNP, currently not on your haplotree, but it lies downstream of L25. Within L70 we find the main group of haplotypes represented by DYS450=9 and DYS445=6 as modal. The DYS445=6 deletion appears to have occurred in L25* before the L70 mutation. At this time no SNP has been found specifically related to the DYS445=6 deletion.
Within L70 there are 2 additional SNPs: M137, M318, defining subclades of L70. These appear to be relatively rarely occurring. However if you are L70 then you should test these SNPs too at some point.
With time and enough members joining our group and testing SNPs and markers we will have the genetic structure of the J-L24 clade well defined.
