| Modern Genetic Analysis Chapter 16. The Genetic Basis of Development Binary Fate Decisions: the Germ Line Versus the Soma Figure 16-11. The early development of C. elegans showing the early lineage divisions of the zygote. The mature cell types that arise from the various daughter cells of the early divisions are indicated. Note that the entire germ line comes from the P4 cell. Each of the P cell divisions indicated by an asterisk is asymmetric, and each of the posterior daughter cells inherits all the P granules, which are thought to be germ-line determinants in the worm. The letters (for example, AB, EMS) are symbols for names of daughter cells.
