Genes under potential selection in pigs. a The distribution of fixation index (FST), nucleotide diversity (θπ), and putative regions under selection (Blue for Duroc and Orange for Luchuan) on the 18 pig autosomes. b Enrichment pattern of putative genes under selection in QTL regions that are associated with several important economic traits. Red represents genes located in regions under selection of eastern pigs while blue represents those of western pigs. * represents FDR < 0.05. ** represents FDR < 0.01. c The coding haplotypes of three candidate causal genes with highly differential functional coding variants across eastern and western pigs. d Annotations of highly differential variants under potential selection. e The proportion of genes under potential selection with different types of highly differential variants
