Wprawdzie nie o Y-DNA, ale o kulturze trzcinieckiej, sprzed tygodnia:
https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0282472O genezie tej kultury na naszych ziemiach:
"Most plausibly, after their emergence in the northern lowlands ca. 1800 BC, “Trzciniec” people migrated south-east, colonised the uplands of today’s south-eastern Poland and western Ukraine, keeping those settlement patterns developed in the north".
A stąd można wysnuć wniosek, jaka będzie hipoteza genetyków dot. pochodzenia domieszki WHG w Trzcińcu:
"Some of the communal graves at this site contain equipment that might evidence influences of other cultural groups [...]. This is a broader regularity, also visible at other sites in the uplands of southern Poland and associated with intense contacts between local elites and highly developed communities of the Otomani-Füzesabony culture from the Carpathian Basin and its northern edges [...]. The style of pottery vessels (types of containers, specific ornaments) and bronze items were clearly inspired by “Southern” patterns. Although the exogamy between the TCC populations from Nida Basin and the Otomani-Füzesabony culture communities settled in the Subcarpathian zone cannot be ruled out, the most reliable interpretation of similarities in material culture is far-reaching exchange of amber and metal [...]".
Czyli genetycy nie przyjmą karpackiej genezy tej domieszki; wyprowadzą ją raczej z Polski północnej lub z terenów na zachód od Odry.
