70% of Indian R1a is L657+ (Y3) which does not descend from Andronovo & Sintashta's Z2124, they both come from a common ancestor Z94. L657 was formed in 2300 BCE, before Andronovo, which did not have this subclade.
>On Y-Haplogroup R1a-L657
>Y haplogroup can be determined by analyzing the Y chromosome of a male. The non-recombining portion of Y Chr is passed on only from father to son, and thus paternity can be determined. Once in many generations, one male undergoes one or many mutations in the Y Chr (eg C -> T, G->A, etc) and thus a subclade is born. This mutated subclade will now pass on through his son

>Sample id I6942 is the only R-L657+ (+ means DERIVED or presence for the particular mutation, - means ANCESTRAL or absence of that mutation) found in ancient DNA so far. R-L657 is that subclade of R1a which is now common in the Indian subcontinent and the middle east, but not found in modern Europe or ancient Europe/steppe. The ISOGG name for it is R1a1a1b2a1a. Technically, I6942 is + for R-Y5 (R1a1a1b2a1a1a1~) and R-Y928 (R1a1a1b2a1a1a1f~) which implies that it is + for L657 as well
