Language has relatively little to do with genetics in Europe. Even amongst Basques pre Indo European DNA was mostly replaced on the paternal line. The survival of their language has probably more to due with their subsequent isolation than with anything else. Even the Etruscans (who somehow managed to survive while being surrounded by Indo European cultures on all sides) have about the same proportion of steppe DNA as other Italians.
