At the bottom of this post is a plot for a K = 4 ADMIXTURE analysis
that includes 14 ancient samples from the Americas. Above the plot are
the admixture percentages for the ancient American samples.
The analysis confirms the significant additional Caucasoid admixture in the Chinchorro mummy sample that was detected by the calculator results in my previous post.
The numbers of SNPs available for this analysis for each of the ancient American samples are below.

Note that BC28, BC23, F9, AM72, and MA575 all have fewer SNPs than
the Chinchorro sample, but they all have much less of the Caucasoid
component than the Chinchorro sample. It can therefore be concluded that
the results for the Chinchorro sample cannot be explained as error due
to a low number of SNPs. Negroid Caucasoid Mongoloid Amerindian
