Ashkenazi haplogroups

[Longbowman]

Everyone=everyone, you delusional maniac. Even on the Members' Photos thread we have a dozen comments about your nonsense. Perhaps I will put up a thread.

Now please, stop commenting on my thread. It is very irritating.

Bump.
Some actualizations happend?

R1 22 18.0%

Now I am starting to suspect, that Leftpedia is taking her basic data from 23andme.

But would have to recalculate AJ and SJ together on your own.

pardon?

pardon?

The data is there devided separatly for Ashkenazis
and for Sephardis, so you would have to add them
together to have general percentage, just like that:

Can you infer anything from the frequency of Ashkenazi haplogroups at all, given there was a clear founder effect? I understand you can go into subclade analysis, but that's proven to be pretty hard for mtDNA as opposed to, say, Y DNA (easy peasy). When did the bottleneck supposedly take place? I've read online that it's relatively recently, within the previous millenium (about 750 years ago IIRC), so it would be interesting to see what the haplogroup proportions would have been pre-bottleneck from early (Ashkenazi) Jewish graves in Western and Central Europe (obviously, digging them up is easier said than done).

Also, I understand the founder effect affects things like haplogroup proportions, but if Ashkenazis were relatively non-diverse (to be expected, if Sephardic non-bottlenecked populations are anything to go by) before the bottleneck, would the bottleneck really make that much of a difference in genetic diversity? Finally, if all Ashkenazim are supposedly descended from survivors of this bottleneck, how come mtDNA very noticeably varies from Western and Central Ashkenazim to Eastern Ashkenazim? The trend would seemingly give credence to the idea of Slavic maternal admixture, with mtDNA K decreasing from about half in Western and Central European AJs to only about a sixth in Russian and Ukrainian AJs, and mtDNA H increasing from about a seventh in Polish AJs (don't have the data for Central and Western European AJs) to over a quarter in Russian and Ukrainian AJs. Assuming this mtDNA variation is due to Slavic maternal admixture, why don't Eastern Ashkenazim plot differently to Western and Central Ashkenazim, or do they?

Alternatively, could this be some form of diffusion-like effect, where if (due to inherent internal variation from probability within the system) women of the larger mtDNA haplogroup have more children, it affects the proportion of the mtDNA haplogroup less than if women of the smaller mtDNA haplogroups have more children? I doubt it would be this though, as H was already the second-largest mtDNA haplogroup, and it's relative proportion increased a lot more than the other relatively tiny mtDNA haplogroups, however this is still possible, as due to being more common it is more likely that women having more children would belong to H than one of the lot less common mtDNA haplogroups (but this also applies to mtDNA K, so maybe in this scenario the attenuating factor of decreasing increases of proportion among larger mtDNA haplogroups overrules the idea of women having more children being more likely to belong to the larger haplogroups but in the scenario of mtDNA H, the idea of women having more children being more likely to belong to the larger haplogroups overrules the attenuating factor of decreasing increases of proportion among larger mtDNA haplogroups, and for tiny haplogroups the chance is just too low for the phenomenon described so far occurring due to the tiny haplogroups by definition being a lot less common).

Basically, ignoring the rambling, how much can you infer from Ashkenazi mtDNA, in terms of their subclades, their proportions, and the mtDNA haplogroup variation among AJs across the cline from Western Europe to Eastern Europe, especially considering all AJs seemingly plot more or less identically?

Do you have info is there any J2b1 among these J2s

EDIT: or among Jews at all
