Fig. 2From: Polymorphisms in early neurodevelopmental genes affect natural variation in alcohol sensitivity in adult drosophilaExtreme QTL mapping analysis. Distribution of elution profiles for the advanced intercross population after an acute ethanol exposure (a) and after two ethanol exposures separated by a 2Â h interval (b). Extremes (10Â %) of the distributions were used for extreme QTL mapping and are shown by the shaded areas. Blue bars indicate males, red bars indicate femalesBack to article page
