Gene Expression (IMAGE)
Caption
A comparison of domestic and forest form antennae found that two odorant-receptor genes, Or4 and Or103, are more 'expressed,' or abundant, in the human-preferring domestic mosquitoes (top bar) than in the forest form that feeds primarily on non-human animals (bottom bar). The color scale indicates the level of gene expression with purple standing for the least amount and red for the most. The numbers to the left of the colored bars represent three different colonies of each mosquito form. The slanted line under each gene's name points to the level of expression of that gene in each colony.
