Figure 4. AdmixtureGraph results for each hybrid (KUI, MTX) based on F4 -statistics of populations identified by ADMIXTURE (K = 6). Node abbreviations indicate: CA = coalescence between all M. caurina and M. americana , CC = coalescence between all M. caurina lineages, AA = coalescence between all M. americanalineages, CMX/CIX = coalescence between mainland/insular M. caurina and hybrids, AMX/AIX = coalescence between mainland/insularM. americana and hybrids. OG = outgroup (Martes zibellina ).
