They are not "Muslims" as you call them but Albanians in denial. Its not "Bosnjak DNA project" rofl but Sanxhak DNA project (so modern South Serbia territory where Slavicized Albanians live).
Their genetics has nothing with Bosnian genetics, as their DNA project name implies. Just as they dont live in Bosnia neither have any connection with Bosnia whatsoever.
Also i believe they included some members from Serbian project or from Bosnia that are artificially bringing up the I2a haplogroup percentage.
Their H1 member is obvious Gypsy while they artificially increased percentages of I2a haplogroup just to connect with Bosnia, these guys are unreal and amazing.
Aromanian Vlachs are probably Latinized Natives (J2b2, Ev13 and R1b) and thats why. They become shepherd Vlachs.
Interesting how there is no or very little J-M205 among Romanians and Albanians, even tho its clearly Roman Vlach haplogroup.
It could be because it arrived later thru late Byzantine Empire and they separated themselves form proto Aromanians.
I call them Sandžak muslims because they are not Bosniaks.
I agree with you vast majority of Sandžaklije are of Albanian origin.
There is still Albanian speakers among Sandžaklije, but mostly among older people.
