From: Genetic diversity and selection in Puerto Rican horses
Admixture graph of horse breeds masking components that are very rare in the Puerto Rican Non Purebred (PRNPB) Criollo horses (< 1% of population structure, in gray). As a result, the population components that may have been shared are clearly visible. Data on PRPF and Criollo horses are from the Illumina Neogen Equine Community Array genotyped in this study, and other genotypes are from Petersen et al.13. The admixture components that were very rare (< 1%) or absent in PRPF or PRNRB were discolored by the MixPainer tool14. Capital letters indicate groups highlighted in Fig. 2 and Fig. S2. An admixture plot of horse breeds masking components that are rare (< 5%) in the NPB Criollo horses, as well as the unmasked plot, is presented in Fig. S3 and Fig. S4.
