Fst divergences between ancestral components can be found here.
You need to extract the contents of the RAR file to the working directory of DIYDodecad. You use it by following exactly the instructions of the DIYDodecad README, but always type 'globe13' instead of 'dv3' in these instructions. You can consult the spreadsheet for proportions of the 13 components in different world populations.
Awesome work. It's good to be able to track the various components through different levels of resolution.ReplyDelete
What's most interesting is how the Amerindian component identified at K=4 behaves differently in certain populations. While most of it is soaked into the Atlantic-Baltic component at K=6 for most populations, it remains salient (though split now between different East Eurasian components) in Finns and other Y haplogroup N affected populations. At K=8, Finns are 8.9 Siberian, while most Western Europeans are 0.1 or less. But at K=4 this Siberian element in Finns is described primarily as Amerindian, meaning that this K=4 component isn't homogenous. This supports your palimpsest idea. Also noteworthy is that at K=3, a significantly greater proportion of the K=4 Amerindian component in Finns is described as 'Asian' than is the case for other European populations.
But here's something interesting: If you attempt to find the pre-haplogroup N level of Amerindian in Finns by subtracting the 8.9 Siberian at K=8 from the 12.1 Amerindian + 3.6 Asian at K=4, then the Amerindian level in Finns that can be considered of the same nature as that found in Western Europeans is 6.8 -- about the same as the English and Dutch.
I understand it's not an exact science, but I thought it interesting to note, especially if we're considering a NE European origin of this component.
Are the Athabaskan samples of northern or southern Na Dene-speaking populations?ReplyDelete
