Fig. 2From: Genetic diversity and structure in Arapaima gigas populations from Amazon and Araguaia-Tocantins river basinsLoci analysis for 392 SNPs across 60 individuals analysed from the five populations of Arapaima gigas. a Frequency distribution of FST values. b Detection of loci under selection (outlier) using hierarchical structure model implemented in Arlequin v. 3.5.2.2. Outlier loci are indicated in red (P < 0.01) and blue (P < 0.05) dotsBack to article page
