Abstract Background Long-term selection 45 generations for low or high juvenile body weight from a common founder population of White Plymouth Rock chickens has generated two extremely divergent lines the LWS and HWS lines. In addition to a 9-fold difference between lines for the selected trait large behavioural and metabolic differences between the two lines evolved during the course of the selection. We recently compared gene expression
