XPEHH/BFS.UGS/3/1

This page describes a signal of selection found in the Burkina Faso An. gambiae population when compared with the Uganda An. gambiae population using the XPEHH (Cite et al. 20XX) statistic.The focus of this signal is on chromosome arm 3R between positions 28,320,000 and 28,360,000. The evidence supporting this signal is strong (\Delta_{i} >= 100 on both flanks).

Signal location. Blue markers show the values of the selection statistic. The dashed black line shows the fitted peak model. The shaded red area shows the focus of the selection signal. The shaded blue area shows the genomic region in linkage with the selection event. Use the mouse wheel or the controls at the top right of the plot to zoom in, and hover over genes to see gene names and descriptions.

Genes

No genes overlap the focal region.

Gene AGAP009183 (defective proboscis extension response) is within 50 kbp of the focal region.

Key to insecticide resistance candidate gene types: 1 metabolic; 2 target-site; 3 behavioural; 4 cuticular.
