Baltics and West Russia is place of 0 Gedrosia..[/QUOTE
We are speaking of Past. Things changed more than a time meanwhile. As I already said in ancient times some countries could have been run across by more than an ethny before these ethnies begun to cross one with another, aside some females rapts. I see Y-R1b-U106 or future U106 passing South the Baltic, maybe without too much contacts with sedentary ex HGs neolithicized population which had NO 'gedrosia' when the U106's had. its possible the most of ex-HGs Y-R1a of North did not have ancient 'gedrosia'. And perhaps it was the same cas with Y-N1 people speaking finnic-uralic, who could have reinforced this lack of 'gedrosia'
The today Baltic speaking people are not only primary I-Ean speakers and their 'ANE' was without 'gedrosian ANE', possibly.
I see Corded entering Scandinavia, at first without too much contacts with the stayed aback populations of South Baltic shores (Y-I1?) and no more contacts with first Y-R1b-U106. More than a wave entered Scandinavia after first Neolithic people. I think the most of the fusion between Y(R1b, Y-R1a and Y-I1 occurred in or around southern Scandinavia during Bronze, before creating Jastorf culture? the 'west-asian- or 'gedrosia' component were perhaps stronger in Scandinavia before the Germanic concretion and diminshed by I1 (0%)+ R1b (smaller %?) actions?
concerning ancient and current components; I think they have all of them their advantages and defects. Porosity between 'Caucasus', 'east-med', 'gedrosia' and even 'south-asian' in 'west-asian' by instance. old 'south-asian' surely split off into some of 'west-asian', 'gedrosia', even 'caucasus according to runs.
