XPEHH/GWA.BFM/2/1

This page describes a signal of selection found in the Guinea Bissau population when compared with the Burkina Faso An. coluzzii population using the XPEHH (Cite et al. 20XX) statistic.The focus of this signal is on chromosome arm 2L between positions 11,274,895 and 11,354,895. 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

The following 4 genes overlap the focal region: AGAP0051691, AGAP0051701, AGAP005171 (Tctex1 domain-containing protein 4), AGAP005172.

The following 4 genes are within 50 kbp of the focal region: AGAP005165, AGAP005173 (Px serine/threonine kinase), AGAP005174 (nucleoporin SEH1), AGAP005175 (acetyl-CoA carboxylase / biotin carboxylase).

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