Figure 2: Admixture analysis of Z. indianus from different locations.

Each column is an individual, and colors represent assignment to distinct genetic clusters based on all autosomal SNPs outside of inversion. Each row represents a different number of ancestral genetic clusters (k = 2 to 6). FL=Coral Gables, Florida, VA-HPO = Hanover Peach Orchard, Virginia, VA-CM = Carter Mountain, Virginia. African sequences combine five geographic locations from Comeault et al. (2020 & ²⁰²¹). Cross-validation analysis supported k=2 (top row) as the most likely number of ancestral groups.
