At the bottom of this post is a plot for a K = 18 ADMIXTURE analysis
of a global dataset. Above the plot is a table of the average admixture
percentages for the six Middle and South American Indian populations
that show Caucasoid admixture beyond the Caucasoid admixture which is
found in all Amerindians, and which is a part of the Amerindian
components in the analysis below.
In the next six plots, the first bars show the average relative admixture proportions for the Caucasoid components in each of the six Amerindian populations with additional Caucasoid admixture. The remaining bars are for the 20 populations whose average relative Caucasoid admixture proportions are closest to those for each of the six Amerindian populations, in order of decreasing similarity.
The plots show that the makeup of the additional Caucasoid admixture in the Quechuas, Bolivians, and Mayans is similar, and that the Spanish are at or near the top of the rankings of the Caucasoid populations in their similarity to the admixture in these three populations.
The Spanish are a bit further down in the similarity ranking for the Mixtecs, and they’re not in the top 20 of the rankings for the Zapotecs and Pimas. This is undoubtedly due to the amount of additional Caucasoid admixture in these three populations being so small that the most similar Caucasoid population cannot be accurately determined.
The table below gives the results of running the ALDER program to determine when the six Amerindian populations received their additional Caucasoid admixture. The admixture dates were calculated assuming that there are 29 years to a generation, and that the sample individuals were born in 1980. All of the estimated admixture dates are in the 17th or 18th centuries.
Although these results provide no evidence that Middle or South American Indians have admixture from the White Gods, they also cannot completely rule it out. But if there is any admixture from the White Gods in these Indians, the amount of it must be much smaller than the amount of admixture from the post-Columbian Spanish. This would make sense, given that the Spanish, with their modern ships, came to the Americas in much larger numbers than the White Gods did, in their more primitive oceangoing vessels.

The results of these analyses make it clear that the additional
Caucasoid admixture in Middle and South American Indians is primarily
from the post-Columbian Spanish, and that I was wrong in the past for
believing that it wasn’t.Although these results provide no evidence that Middle or South American Indians have admixture from the White Gods, they also cannot completely rule it out. But if there is any admixture from the White Gods in these Indians, the amount of it must be much smaller than the amount of admixture from the post-Columbian Spanish.
