Fig. 2From: Genome-wide identification of functional enhancers and their potential roles in pig breedingDistribution of functional enhancers in the pig genome. A-B Distribution (A) and relative enrichment (B) of functional enhancers in pig genomic regions. FC, fold change. C Number of genes expressed at different levels. Genes were classified with or without enhancers, which is based on whether an enhancer was in its proximity. Genes are classified into four groups according to their expression level. Silent, FPKM = 0; low, 0 < FPKM ≤1; medium, 1 < FPKM ≤10; high, FPKM > 10Back to article page
