WebThe movement of chromosomes and the changes in spindle size have been recorded in living spermatocytes of the grasshopper during the meiotic divisions. Anaphase movement consists of two separate processes which are related to the action of distinct cellular organelles: (1) The shortening of chromosomal fibers moves the chromosomes … WebDuring anaphase, the chromosomes start separating and moving from the equatorial plate of the cell. At the end of this stage (late anaphase), the sister chromatids completely separate and reach the opposite poles of the cell. In this stage, it's also possible to clearly identify the chromatids given that the process occurs in the cytoplasm.
