Notizen:
The numbers of primary spermatocytes within cysts as well as numbers of postmeiotic spermatids in bundles in Drosophila hydei were determined. Within the contents of a single testis the cysts of primary spermatocytes are found to contain 5-11 germ cells. Furthermore, the number of spermatocytes per cyst is age-dependent, in that pupae have a mean of 8.1 cells whereas fertile adult males have a mean of 7.1 cells. Counts of spermatids in section of testes add further support to the view that the primary spermatocytes, from which the spermatids originated, were not formed in a strict geometric progression.
