Abstract

Although embryogenesis appears to be determinate in C. elegans because of its stereotype cell lineage, the mechanisms of regional specification typical for indeterminate development are nevertheless used. Early on, blastomere identities are specified by binary decisions, and each blastomere gives rise to a coherent region of the embryo containing different somatic cell fates.
