Inter-individual variation among worms in a shared environment. Caenorhabditis elegans

Isogenic individuals growing in the same environment often show substantial phenotypic variation. The causes, consequences and molecular bases of inter-individual variation are usually poorly understood. To characterize molecular differences between isogenic individuals, we measured genome-wide expression profiles in synchronized single young adult C. elegans worms. Overall design: 41 individual N2 C. elegans were grown at 20˚C and collected 46h after hatching
