Influence of past migratory events in Croatian female and male genetic legacy

Numerous studies of mitochondrial and Y chromosomal biallelic markers have resolved major prehistoric routes of the settling of Europe and proved that the majority of European gene pool has Paleolithic genes. In order to determine the extent of Paleolithic vs. Neolithic impact among Croatian maternal and paternal lineages, we analyzed biallelic markers diagnostic for main Eurasian haplogroups in 457 Croatian Y chromosomes and 721 mitochondrial DNA of inhabitants from various Croatian regions (mainland and four eastern Adriatic islands: north-Krk ; south-Brac, Hvar and Korcula). If Y chromosomal haplogroups: J-12f2, G-201, E-SRY4064 and mitochondrial J and T1 are considered as major Neolithic markers, the majority of females and males in the investigated population are carrying Paleolithic haplogroups. Overall, frequency of mitochondrial Neolithic markers is 11.5% whereas Y chromosomal Neolithic impact is 13.1%. When investigated populations are analyzed separately, the highest mitochondrial Neolithic impact is noticed in mainland population whereas the lowest is on the island of Korcula. For Y chromosomal markers, the lowest Neolithic impact is noticed in mainland population and the highest on the islands of Krk and Korcula. We will discuss these results in the light of evolutionary forces that could cause these differences as well as in the light of archeological data that can prove material evidence of Paleolithic and Neolithic legacy in the investigated area, both mainland and islands.
