Комментарий ув. пана Милевского насчет Y2613:
This clade is apparently associated with deep Slavic ancestry. However, since there is no common agreement regarding the most likely location of the hypothetical Proto-Slavic homeland, there is also no consensus regarding the place of origin for clade Y2613.
Personally, I am favouring the most widely discussed hypothesis about the possible association of those hypothetical Proto-Slavs with the so-called Kiev culture, which would place the origin of all relatively large "Slavic" subclades in a region encompassing Southern Belarus, Northern Ukraine and the neighbouring part of Russia. Since Y2613 is most common in the Carpathian region and in the Western Balkans, we would need to assume that most of the early Y2613 members were at some point included in the South-Western group of the Early Slavs who expanded first towards North-Western Ukraine (Korchak-Praguge culture) and then towards the Carpathian region (including SE Poland, Slovakia, Hungary, Moravia and Bohemia) and further south-west towards the Western Balkans (Slovenia and Croatia). However, it should be noted that there are also some relatively small subgroupings of Y2613 that are associated with a very different pattern of geographical distribution. This includes, for example, the so-called Northern cluster under Y2609 (marked as Y2609*-A in our project) that seems to include those early Y2613 members who have migrated north (including north-west and north-east) from their previous settlements in the Proto-Slavic homeland (in Southern Belarus?), and I expect to find more such sublineages under Y2613, Y2609 and Y2608 that are not associated with a typical Carpathian-Dalmatian distribution pattern.
When assuming that the so-called White Croatia (ie. a region encompassing SE Poland and the neighbouring part of Ukraine) had anything to do with the hypothetical Old Croats migrating from the Carpathian region to Western Balkans, one can also suspect that clade Y2613 was one of the major Y-DNA clades present in those hypothetical Early Medieval Old Croats who are supposed to have initially lived somewhere north-east of the Carpathian range. In addition to Y2613, there are of course many more "Slavic" subclades that could have been quite common among those Old Croats, and this includes I2a-CTS10228, R1a-Y2902>Y3226, R1a-P278.2 and R1a-YP371.
