F _ST analysis of the chromosomal region containing the Neuroligin-3 gene. a) Plot of F _ST (Reich-Patterson formulation) between Desert and Plains bees at 4,507 SNPs in a 200-kb interval on Chromosome 9 (Group9.10) that spans the first two exons of the Neuroligin-3 gene (GB42603; blue rectangles; transcribed right-to-left). Orange rectangles indicate the two exons of annotated gene GB42882, putatively transcribed on the opposite strand, though we find the evidence for existence of a functional gene unconvincing. Genome-wide, 10 % of the F _ST values are larger than 0.20 — indicated with red. Light blue bars represent non-significant F _ST values. b) The interval 3,143,154-3,143,747 has a statistically significant concentration of SNPs with F _ST in the highest 10 %, meeting our criterion for putative positive selection by the F _ST criterion
