Why South Slavs from Dinaric Alps have low percentage of R1b?

[Tauromachos]

R1a in Greece=Slavic.
R1b=Dorian,Illyrian,paleobalkan and maybe Celtic

Nope

[Livin]

Nope

Then what?

[Tauromachos]

Then what?

R1b is not clear who brought it some say its Celtic as you also mentioned
anyway its significantly more in Greeks than R1a and more distributed allover Greece

Both haplogroup are low in Greece and Albania if I remembere well.
The r1b in Greece has to do with Dorian IMO and with foreign elements like Celtic invasion in balkans,illyromacedonian relations and maybe Anatolian folks who come here as soldiers or Slaves during Hellenistic years.As for r1a is definelty slavic.
Turkey also has more r1b because of ancient anatolians(Hittite,Luwian).

Majority of R1a brances in Greece are Slavic.
Most common branch of R1a in Greece is M458, and that is a typical Slavic branch.

If they are Slavic then they didn't exist in premedieval Greeks.

Weren't Illyrians R1b? If not, can someone name their R1 subclade?

Yes, main Illyrian marker was R1b L23 (found in bronze age Panonnia), also J2b2 (found in bronze age Dalmatia) and probably others, most importantly E-V13.

M458 and Z280 came to Greece with Slavic expansion.
Maybe there is some other branches of R1a in Greece which are paleo-Balkanic, I don't know.
If Greeks have Z93 it can be paleo-Balkanic, because R1a-Z93 was found in ancient nacropolises ikn Bulgaria. Those are probably proto-Thracians.

I believe R1b are Barbarian invaders. Rome lost Gaul and Italy in 5th and 7th century A.D to many barbarians.
I've always believed that Albanians as well as South Slavs are much more native to the region than French or British people are to their regions.
After all, Illyrians and Thracians were extremely Poor people, barbarians were after Gold therefore they did not settled in poor provinces.

No. Northern Dinaric alps experienced most population turnover, some places in dinaric alps are like 90% slavic paternally. Region also experienced many migrations, genocides and population turnovers.

Dinaric alps are also place where original Croats settled in our case, first Croatian Kingdom was founded in dinaric zone.
