Do 31% of Greeks have Celtic roots?

Today’s Macedonians are descendants of the Antic Macedonians, says research results from the Swiss Genealogy Institute iGENEA. For a second time an independent research institution confirms what Oxford and Madrid University confirmed a decade ago. iGENEA is the most famous global Genealogy institute who once again frustrated the Greek government by confirming the direct connection between the Macedonians today and in Antic times. The question came from a Greek citizen who asked iGENEA the following question: "What are the roots of today SlavMacedonians". The Institute responded: "Before all, they are Macedonians, not slavMacedonias as you referred to them for political reasons. The largest part of the Macedonians are direct descendants of the Antic Macedonians. Only a minor portion have a Slavic connection". iGENEA backed up their findings with hard numbers. However, tying the today's Macedonians with Antic Macedonians is not the only disappointing information for Greece. According to iGENEA, only 32% of Greek citizens have Macedonian, Hellenic and even Arab origin. iGENEA further explains that 31% of Greek citizens have Celtic roots, 12% Germanic and Slavic origin, while 11% have Illyrian roots. iGENEA also negated the Illyrians roots of the Albanians. In stark contrast to Albanian beliefs, IGENEA says the Albanians have the least Illyrian roots. Only 20% of the Albanians have Illyrian roots, while 40% of today’s Bosnians have Illyrian roots. In the past several months, the iGENEA Genealogy Institute had been flooded with requests by Greek Citizens who, ironically, did not care for their own origin, but all questions were aimed at the Macedonians' origin. iGENEA in its research uses DNA analysis, historical, archeological, and anthropological sources.
