Two separate classes of movements occur duringanaphase. During the first part of anaphase, the kinetochore microtubules shorten, and the chromosomes move toward the spindle poles. During the second part of anaphase, the spindle poles separate as the non-kinetochore microtubules move past each other. ...

–Sisterchromatidsremain attached at the centromere until anaphase II. • The processes during the second meiotic division are virtually identical to those of mitosis. • Mitosis produces two identical daughter cells, but meiosis produces 4 very different cells. ...
