Anaphase II
Note: Ana is a Greek word meaning, among other things, back, which to Adolf Strasburger, the namer of this phase, referred to the chromosomes moving back into compacted nuclei.

Note: Meiosis II is very similar to mitosis. The primary difference is that in meiosis II only one member of each homolog pair is present, whereas in mitosis both are.

During anaphase II, the third step of meiosis II, the sister chromatids of each chromosome separate and move toward opposite poles. Once they are no longer connected, the former chromatids are called unreplicated chromosomes. As the chromosomes are dragged along by the spindle apparatus, their arms can be seen dragging along behind so that the chromosomes form V-shapes. The poles themselves move further apart as cytokinesis begins and the cell lengthens (not shown in figure).
