Fig. 2From: Comparison of ultraconserved elements (UCEs) to microsatellite markers for the study of avian hybrid zones: a test in Aphelocoma jaysSTRUCTURE results (K = 2). STRUCTURE analysis based on (a) 2468 UCE SNPs, (b) 13 microsatellites [15, 21]. The y-axis indicates assignment probability to either the Aphelocoma californica genetic cluster (gray) or the A. woodhouseii genetic cluster (blue). Each colored vertical bar represents a vouchered museum specimen and numbers along the x-axis indicate distance (km) along the sampling transectBack to article page
