WebFeb 1, 1996 · During mitotic and meiotic divisions in Dermatobia hominis spermatogenesis, the germ cells stay interlinked by cytoplasm, bridges as a result of incomplete cytokinesis. By the end of each division, cytoplasmic bridges flow to the center of the cyst, forming a complex, called the fusoma. During meiotic prophase I, spermatocytes I present ... WebSep 30, 2024 · Telophase I varies between males and females. Cytoplasmic division in females occurs asymmetrically and produces a small polar body and a much larger primary oocyte. In males, the cell division is incomplete and spermatocytes retain a cytoplasmic bridge. Although the resultant cells are diploid, they are not identical to the parent cells …
