We are aware of one demographic scenario in which the ALDER test could potentially return a finding of admixture when the test population is not in fact admixed.
Long's [ 30] test for heterogeneity of admixture rejects the null hypothesis of neutral admixture when the tails of the empirical distribution of admixture estimates are thicker than expected from the variance.
Since mapping information is available for this dataset, which can be used for LD-based SNP-pruning purposes, we also investigated the performance of PSIKO, sNMF, and ADMIXTURE when the sequences are pruned.

One such application is to greatly enhance detection of genomes containing ethnic admixture even when the amount of admixture is small.
Also, limestone powder is found to be the best mineral admixture when it replaces a part of cement, where more fluidity is exhibited caused by the dilution effect.
Whereas an excess of females from a given source population might be viewed as generating elevated X-chromosomal admixture, when both populations have a sex bias in the same direction, the source population with the larger sex bias dominates the signal.
There are also multiple reasons why the three-population test can identify admixture when ALDER does not.
If the error structures of the archaic DNA and one of the modern human DNA samples are similar to each other for one of many reasons, the ABBA-BABA test could report admixture when it did not in fact occur.
Studying three lakes, they found low replacement of native gene pools, when natural recruitment of zander was high, but they observed extended replacement and high levels of admixture, when self-recruitment was low.
In Table 3, we illustrated targeted RHH analysis of 14 simulated ethnic outliers merged with the 58BC dataset, and our mathematical model also showed enhanced RHH sensitivity in detecting and visualizing small percentages of genome admixture when one or a few targeted subjects are added to a large, unadmixed reference panel (see SUPPLEMENTARY DISCUSSION).
