FIG. 2. Wachtliella (Cecidomyidae, Diptera). Diagram of normal cleavage (a, maturation plasm black), isolation (b-d) and translocation experiments (e-k) (after GeyerDuszynska, 1959). Scale: percentage of egg length (Total length, 0-4 mm). Nuclei white
before, black after elimination; the number of nuclei eliminating chromosomes during
IVth mitosis is shown at the right of each egg. The fate of the nucleus reaching the
posterior pole is indicated beside that pole. Stratification beginning from centripetal end
(e-k): Grey, yellow, and orange zones; white cap (in k only). Further explanation in the
text.
