Estimating Primordial Cell Numbers in Drosophila Imaginal Discs and Histoblasts,or example, is formed from the second leg imaginal disc and the prothoracic leg by the prothoracic leg disc. The critical observation for us is that adult structures, populated wholly by imaginal disc descendants, can be genetically mosaic (Sturtevant, 1929). This has been interpreted as an indicati

(e.g., Pak, 1975), one could ask if this kind of mutant is defective in a process such as membrane permeability changes, caused by light-induced changes in photopigment conformation. The eventual aim is to lea

Estimating Primordial Cell Numbers in Drosophila Imaginal Discs and Histoblasts, nuclei prior to blastula stage are held together in a syncytial mass; both indirect (fate maps) and direct experiments (nuclear transplantation) show cleavage nuclei to be without developmental specificity. The suggestion has been made that earliest determination occurs at the blastula stage (Chan

Cell Lineage Relationships in the Drosophila Embryo,cal example of such cell groups is the imaginal discs, clusters of cells in the larva determined to form specific regions of the adult. Because the discs cannot be identified in early stages during embryogenesis, their origin and early development can best be studied using cell lineage techniques su
