Fig. 5. Genetic relationship of Mexican Native populations with the ancient genomes of USR1 and Anzick-1.
a Maximum-likelihood tree inferred from allele frequency, residual plot from the maximum-likelihood tree is shown. b Possible tree topologies resolved by D-statistics. c D-statistic in the form of D(Yoruba, USR1; Mex Nat, Karitiana) shows that all Mexican populations are related to the USR1 genome. d D-statistic in the form of D(Yoruba, Ancient; Mex Nat, Karitiana). Error bars in c, d represent 3 standard errors estimated by a weighted block jackknife. Mex Nat Mexican Native population.
