Variation in the embryonic cell lineages of Caenorhabditis elegans natural populations

Charlotte Weymer, Ryan L Johnson, Jane Olivia Helou, Eric J Deeds, Erik C Andersen, Pavak Kirit Shah

The paper quantifies developmental variation in C. elegans natural populations using embGAN, finding genotype-specific differences in cell-cycle timing that exceed within-strain variation.
