Greek people, particularly island and southern Greeks have a completely different Haplogroup picture than the rest of the Balkans (with parts of Albania excluded).

Now they’re not clear on their exact reasoning, but Slovenia is part of the Central European grouping (which in and of itself is controversial, but never mind) because of its R1A Haplogroup dominance. That’s fine, but northern Croatia falls in the same category, yet it’s part of the Balkan and Greek group.

Moreover, there is a notable absence of referral to Slavic genetic makeup in the description of “Greek and Balkan”. The picture above shows presence of the I2A Haplogroup (couldn’t find a more precise map of sub haplogroups). Long story short, through ancient genetic testing and what we know of the founder effect, over 90-95% of most ex-Yugoslav countries have ancestry from western Ukraine or Southeast Poland.

I really don’t get what it’s supposed to tell you. Why are those countries in one group together and not instead separated into Greek, Albanian, and some Slavic grouping? If someone adopted is from Podravina (historically) and tries to find out more about where they’re from only to be told they are “Greek and Balkan”, that is very, very misleading.

I don’t get why it’s called “Greek and Balkan”, I don’t understand the need to differentiate “Greek” if it’s already one grouping and I don’t know why they grouped them together in the first place.
