Table 1.
Genotypes, allele frequencies, and geographic locations of the Native American populations investigated.
Table 2.
Zea pollen relics ages and 230Cys*ABCA1 populations frequencies used for the regression analysis.
Figure 1.
Plot of the joint FST and He distributions for the Mesoamerican agriculturalist versus South American (agriculturalists + hunter-gatherer/foraging) groups.
Each dot indicates a SNP (listed in item c.2 in the Materials and Methods section). The lines represent confidence intervals. Only the ABCA1 locus showed significance at the 5% level (filled blue circle). Five selected SNPs were not plotted in the figure because of monomorphic sites in all subdivisions, missing data, and/or dot superposition.

ABCA1*230Cys frequencies versus radiocarbon ages of maize domestication (Zea pollen relics; Blake [42]).
Spearman’s rho value = 0.936975 and p = 0.0019.
