Patterns of hybridization within felid lineages. (A) Ocelot lineage, showing the discordant position of the northern tigrina (green) between nuclear (red) and mitogenome (black) phylogenies. Within the species tree is shown nuclear (red) and mitogenome (black) genealogies, with dashed red lines indicating genomic evidence for ancient hybridization (not scaled to time). (B) Asian leopard cat lineage, showing the discordant position of the fishing cat (green) relative to the Asian leopard cat populations in nuclear and mitogenome trees. (C) Domestic cat lineage, showing the results of admixture tests based on whole-genome SNV alignments which reveal two strong introgression signals (a and b) across the whole genome of Felis species. (D) Panthera lineage, showing the discordant position of the snow leopard (green) between nuclear and mitogenome phylogenies. Admixture tests from whole-genome SNV alignments support gene flow from the lion/leopard lineage to the snow leopard. Note the significantly skewed D-statistic for the X Chromosome (right).
