Time lapse movie of meiosis in spermatocytes of the Locust Psophus stridulus showing telophase of meiosis I, cytokinesis, interphase, and prophase of meiosis II. This is a historic movie made in the early 40s by Kurt Michel of the Zeiss company in Jena using Zernike's newly invented phase contrast microscope. Despite its early date, the movie and the others in the group remain some of the clearest examples of chromosome behavior during meiosis.
The movie was originally recorded on 35mm film, and later transferred to CD format. The text at the beginning of the movie translates approximately as follows: Meiosis division I, telophase and meiosis II, prophase. (Interpase ca. 6-7 hr) ----------------------- See also: Michel, K.
