What are Ashkenazis mostly descended from?

[Sikeliot]

Here is K=12

Ashkenazis, Sicilians in that order

Atlanto-Baltic: 30.1, 31.3
West Asian: 23.4, 23.5
Southern: 43.1, 42.8

[Formozgan]

Khazars, Egyptians, Arabians, Mesopotamians, Mediterraneans and various central and other eastern european.

[Anglojew]

Levantine-European hybrid population.

Judging by Ashkenazi genetics, one of two things must be true.

1) You guys coincidentally have a similar mixture to southern Italians due to similar admixture components,
or
2) You are mostly descended from southern Italian converts, with enough ancient Israelite in you that you have a very slightly higher SW Asian score (but, interestingly, everything else is fairly constant).

That doesn't make any sense. How would south Italians, and Israelites create a mix that clusters with south Italians? Ashkenazis have a significant amount of German, mixed with South Italian, and Israelite.

Khazars, Egyptians, Arabians,

Genetic evidence doesn't support that.

[Smaug]

From the mixture between Israelite women with native Baltic/Germanic/Slavic males.

Is there a such thing as an original Jew anymore, Jews are way to mixed.

[Pjeter Pan]

Idk the ones from the Old Testament

According to the "Old Testament" the Israelites were descendants from Abraham who was born in Ur (Mesopotamia). Are original Jews in fact Mesopotamians?
