M. Belledi et al., Maternal and paternal lineages in Albania and the genetic structure of Indo-European populations, EUR J HUM G, 8(7), 2000, pp. 480-486
Mitochondrial DNA HV1 sequences and Y chromosome haplotypes (DYS19 STR and
YAP) were characterised in an Albanian sample and compared with those of se
veral other Indo-European populations from the European continent. No signi
ficant difference was observed between Albanians and most other Europeans,
despite the fact that Albanians are clearly different from all other Indo-E
uropeans linguistically. We observe a general lack of genetic structure amo
ng Indo-European populations for both maternal and paternal polymorphisms,
as well as low levels of correlation between linguistics and genetics, even
though slightly more significant for the Y chromosome than for mtDNA. Alto
gether, our results show that the linguistic structure of continental Indo-
European populations is not reflected in the variability of the mitochondri
al and Y chromosome markers. This discrepancy could be due to very recent d
ifferentiation of Indo-European populations in Europe and/or substantial am
ounts of gene flow among these populations.
