Haplogroup J2 and Illyrians.
"Paternal genetic heritage was studied on DNA from 1,141 individuals analyzed for Y chromosome markers (data from the Institute for Anthropological Research, Zagreb, Croatia and from the published sources) (Barač et al., 2003; Rootsi et al., 2004; Peričić et al., 2005a, 2005b). The individuals were from the continental parts of the Balkan peninsula, the north-west Adriatic and the south-east Alpine areas as well as from the Eastern Adriatic islands, i.e. the areas where the different Illyrian trybes settled during the Iron Age period (Fig.1). The sample was analyzed for Y chromosomal haplogroup frequencies in 9 populations and classified as I1a, I1b*-P37, R1a-SRY1532, R1b-M173, E3b1-M78 and J2e1 haplogroups."

"The two haplogroups most strongly associated with Albanian people (E-V13 and J2b) are often considered to have arrived in Europe from the Near East with the Neolithic revolution or late Mesolithic, early in the Holocene epoch. From here in the Balkans, it is thought, they spread to the rest of Europe."

"The origin of the Albanians has been for some time a matter of dispute among historians. Most historians conclude that the Albanians are descendants of populations of the prehistoric Balkans, such as the Illyrians, Dacians or Thracians. Little is known about these peoples, and they blended into one another in Thraco-Illyrian and Daco-Thracian contact zones even in antiquity."
