Abstract
The ovaries of triploid intersexes are characterized by tumors that contain hundreds of cells, many of which are mitotically active. These cells resemble germarial cystocytes in that they are often interconnected by ring canals and can sometimes differentiate into endopolyploid cells that resemble ovarian nurse cells. More rarely a tumor cell will follow the oocyte developmental pathway and form organelles such as synaptonemal complexes and annulate lamellae. 2X 3A cystocytes do not decrease in volume with each consecutive division as is normally the case. Since the value for the number of ring canals per 100 sectioned tumor cells from 2X 3A intersexes is only about 70% the value for normal germarial cystocytes, we conclude that the cystocytes from intersexes often undergo complete cytokinesis. Thus the cystocytes of intersexual ovaries show the same abnormalities of cytokinesis that characterize females homozygous for the female sterile genes fs (1) 1621, fs (1) 231, fu and fes.
