Drosophila melanogaster lines were kept during one (F1) or ten generations (F10) on C18∶0- or C18∶1-rich food. F9 individuals kept on either fatty acid were transferred at the beginning of the 10th ge
The specific genes regulating the quantitative variation in macronutrient preference and food intake are virtually unknown. We fine mapped a previously identified mouse chromosome 17 region harboring
