Population Genetics: Sallis Right Once Again

And other news.

Read this.  Emphasis added:

Consider genetic ancestry testing performed on an individual we will call Joe, whose eight great-grandparents were from southern Europe. The HapMap populations are used as references for testing Joe's genetic ancestry. The HapMap's European samples consist of “northern” Europeans. In regions of Joe's genome that vary between northern and southern Europe (such regions might include the lactase gene, LCT [MIM #603202]), the genetic ancestry test using the HapMap reference populations is likely to incorrectly assign the ancestry of that portion of the genome to a non-European population because that genomic region will appear to be more similar to the HapMap's Yoruba or Han samples than to its (northern) European samples…

…European populations, for example, despite revealing genetic differences, have been shown (as described above) to exhibit mainly continuous spatial patterns of variation. When admixture is estimated for European individuals under the assumption of two ancestral populations, the method chooses admixture proportions that make individuals a mixture of “northern” and “southern” ancestral populations even though there is no independent evidence that two such ancestral populations ever existed…

…To infer ancestry, researchers rely on comparing any individual's particular genetic profile to that of reference populations. Research geneticists benefit from various publicly available databases such as the HapMap, Human Genome Diversity Panel, Perlegen Human Genome Resources, POPRES project, and Seattle SNPs projects. However, even the databases that researchers consider the most applicable reflect a woefully incomplete sampling of human genetic diversity, and this has important consequences for the accuracy of ancestry inference. One problem is that the “ancestral populations” assumed by some methods are not explicitly represented in databases—and indeed cannot be represented as such because we do not have the ability to sample ancestral populations…

…The scientific claims of companies that choose not to disclose the contents of their proprietary databases cannot be assessed; therefore, the reliability of the information they provide to consumers cannot be verified.

That basically confirms the various criticisms I have made about ancestry testing and Der Movement's misrepresentations and lies about population genetics.  Thus, Sallis right once again.

See this.

Conclusion: The consistency of consumer genetic testing is high for ancestry results within companies but lower and more variable for ancestry results across companies and for specific traits. These results raise questions about the usefulness of such testing.

Of course the within company results will be consistent for identical twins – essentially the same as testing the same person twice, with the same methods and, most importantly, the same reference populations (or lack thereof). The key finding is the lack of concordance for between company testing - this clearly demonstrates that methodology, and above all else, reference populations, used, will significantly alter results.  Sallis right once again.

Guide for Der Movement on how to lie about population genetics.

Fetishism alert  Northern Italian Southern Italian.

More evidence that Der Movement has nothing to offer White ethnics.

Is this Yukio Mishima?  No, Mishima actually looked more like a White man.

I tuned in briefly to the Johnson-Kessler livestream, just in time for Johnson to start bringing up...you guessed it...Richard Spencer. I can't fault the criticisms of Spencer, but it is essentially the pot calling the kettle black. Johnson and Spencer are like two scraggly mice fighting over the same small piece of moldy cheese.  They and their asinine Alt Right wrecked American racial nationalism and now we have the wreckers squabbling over their piece of the ruins.
