Fig. 7From: Analysis of polygenic selection in purebred and crossbred pig genomes using generation proxy selection mappingUpset plot showing the number of GPSM significant SNPs across populations. Each vertical blue bar shows the number of GPSM significant SNPs that are unique to a single population (25–89 SNPs), unique across two populations (2–25 SNPs), unique across three populations (2–13 SNPs), or unique across all four populations (4 SNPs). Horizontal gray bars present the number of GPSM significant SNPs for each genetic lineBack to article page
