Terminal filaments are present in the larval ovary of tsr² homozygotes and tsr¹/tsr² animals. Terminal filaments are present in the larval ovary of tsr²/tsr^ntf animals.

At early stages of oogenesis actin filaments are seen in clumps throughout the tsr mutant egg chamber.

A significant proportion of homozygous and tsr¹/tsr² larval neuroblasts are polyploid. The mitotic index and number of mitotic cells in anaphase is nearly normal, and chromosomes appear morphologically normal. The two asters of homozygous primary spermatocytes remain in close proximity to each other at the M1a stage, and do not associate with the nuclear envelope. After the M1 stage, the asters progressively resume a relatively normal position and the spermatocytes appear indistinguishable from wild-type throughout the remainder of the first meiotic division. Prophase/prometaphase secondary spermatocytes show the same defect in aster migration and positioning as that seen in the primary spermatocytes at stage M1. The spindles become more normal by metaphase II, and retain a wild-type appearance throughout the remainder of meiosis II. 4.4% of spermatids contain an abnormal sized Nebenkern and more than one nucleus. The distribution of actin during meiosis is abnormal in spermatocytes.
