Abstract Background Locomotion is an integral component of most animal behaviors and many human health problems are associated with locomotor deficits. Locomotor behavior is a complex trait with population variation attributable to many interacting loci with small effects that are sensitive to environmental conditions. However the genetic basis of this complex behavior is largely uncharacterized. Results We quantified locomotor behavior of Drosophila melanogaster in a large population of inbred lines derived from a single natural population and derived replicated selection lines with different levels of locomotion. Estimates of broad-sense and narrow-sense heritabilities were and respectively indicating substantial non-additive genetic variance for locomotor behavior. We used whole genome expression analysis to identify 1 790 probe sets with different expression levels between the selection lines when pooled across replicates .
