 * The last chapter showed severe limitations in the concept of 'mosaic' development as it applies to spiralian embryos. It did, however, demonstrate differential segregations occurring at cleavage there, and seen for visibly distinct plasms, some macromolecules and determinants inferred from experimental studies.
