Genome-wide association (GWA) analyses in humans have implied many genes in the control of height but suffer from the inability of controlling the environment. Genetic analyses in Drosophila have identified conserved signaling pathways controlling size; however, how these pathways control phenotypic diversity is unclear. We performed GWA of size traits using the Drosophila Genetic Reference Panel of inbred, sequenced lines and find that top variants are predominantly sex-specific; do not map to canonical growth pathway genes, but can be linked to these by epistasis analysis; and are enriched in homologs of genes involved in human height regulation. Performing GWA on well-studied developmental traits under controlled conditions expands our understanding of developmental processes underlying phenotypic diversity. %U https://www.biorxiv.org/content/biorxiv/early/2015/04/10/017855.full.pdf
