Figure 3. Principal Component Analysis on the genomic SNPs, colors
represent subspecies and hybrid categories inferred from ADMIXTURE
(K =3). Individuals with q values > 0.95 are
considered genotypically pure individuals for each subspecies (i.e.,S. c. corvina , S. c. hoffmanni , and S. c. hicksii ).
Hybrids that have q values from the third genetic group
< 0.02 and the q from the second genetic group was at
least 2x the value from the third genetic group are labeled by their
mixed ancestry (e.g., corvina x hicksii ). Admixed
individuals with q > 0.1 from the third population
or if ancestries from the second and third genetic cluster where similar
were considered three-way hybrids
