Sternberg ABSTRACT Whereas the hermaphrodite gonad of Caenorhabditis elegans has two symmetric arms (didelphy), the female/hermaphrodite gonad of many nematode species features a single anterior arm (monodelphy). We examined how gonadal cell lineages and intercellular...

...Ralf J. Sommer; Lynn K. Carta; Paul W. Sternberg ABSTRACT The invariant development of free-living nematodes combined with the extensive knowledge of Caenorhabditis elegans developmental biology provides an experimental system for an analysis of the evolution of developmental mechanisms. We have...
