Principal component analysis (PCA) plot of horse breeds incorporated from Petersen et al.13, including Puerto Rican Paso Fino (PRPF) and Puerto Rican Criollo (PRNPB) from this study (both are encircled in the enlarged area). For convenience, the horse breeds are colored according to the phylogeny calculated from SNP frequencies in 38 horse populations from Petersen et al. (2013) (Fig. S2). The index for the abbreviations used here is presented in Fig. S2.
