Population tree of Coccidioides subspecies population splits and mixtures. Maximum-likelihood population tree and presence of gene flow between diverged Coccidioides populations were inferred by using TreeMix software and microsatellites data (34). Direction of arrow indicates migration or gene flow based on admixture models; migration weights are shaded according their importance, supporting gene flow from a soil-derived population (AZSOIL) recovered from animal passage to a clinical-associated

Figure 2. Population tree of Coccidioides subspecies population splits and mixtures. Maximum-likelihood population tree and presence of gene flow between diverged Coccidioides populations were inferred by using TreeMix software and microsatellites data (34). Direction of arrow indicates migration or gene flow based on admixture models; migration weights are shaded according their importance, supporting gene flow from a soil-derived population (AZSOIL) recovered from animal passage to a clinical-associated population (TUCSON). Color-coding for populations: lime green, San Joaquin Valley (SJV); aqua, San Diego/Mexico (SDMX); pink, Texas/South America (TXSA); purple, Mexico (MEXICO); red, Tucson (TUCSON); yellow, Phoenix/Yuma (PHOENIX); orange, soil (AZSOIL). The drift parameter, represented by horizontal scale, measures the variance in allele frequency change along each branch of the tree. The actual source of each evaluated isolate (clinical, veterinary, or soil) is represented proportionally in the pie chart.
