Fig. 5From: Signatures of positive selection in the cis-regulatory sequences of the human oxytocin receptor (OXTR) and arginine vasopressin receptor 1a (AVPR1A) genesDetection of outlier SNPs of the AVPR1A gene using FDIST. FDIST suggests the SNPs rs12830859, rs1587098, rs1580705, rs11174805, rs11174806, rs11174807, rs117072097, rs11174811, rs34462214, rs3021529, and rs7308855 are under balancing selection. x-axis: estimated heterozygosity values; y-axis: F ST -values. The red area indicates positive selection; grey area neutrality, and yellow area balancing selection. Confidence intervals represent borders between “selection areas”Back to article page
