1. How thick in the head are you?? Theres only been two studies done in the world about serbs the peric and american one. The american one finds 20-25% less neolithic genes than peric thats huge. So yes a croat "studying" serbian genes is quite likey to be biased.
wth are you talking about? I took those numbers from this study: http://www.eupedia.com/europe/european_y-dna_haplogroups.shtml
That's an ongoing study which constantly adds the haplogroups found in samples they get from countries, and they just update the chart, has nothing to do with us. Just get over it…you don't have same genetic background as we do for crying out loud.
Eupedia is, lets just say amateurish
