Fig. 2From: Variability in porcine microRNA genes and its association with mRNA expression and lipid phenotypesPrincipal component analysis plots based on SNPs mapping to: a the whole-genome (N = 19,720,314 SNPs), b miRNA genes (N = 285 SNPs), c full 3′UTRs (N = 709,343 SNPs), d 3′UTR 7mer-m8 sites (N = 107,196 SNPs) and e 3′UTR 8mer sites (N = 33,511 SNPs), respectively. The symbol “Q” represents a wild boar sampled from the Middle EastBack to article page
