Phases in Meiosis II

There could be an Interphase II which only happens to certain cells which you could consider as a "rest period", but Meiosis II starts with Prophase II 

In Meiosis II, it has two cells, the nuclear envelope dissolves again, and the chromosomes in the dissolved nuclear envelope have the chromosomal crossover from the father and mother chromosomes, and the centrosomes duplicate and now there are two centrosomes. And they start migrating to the sides of the cell.

Metaphase II still has the two cells, but each cell has two centrosomes and they migrate to the sides of the cell and they are using their "fibres" to connect to the centromere (the things between the chromosomes.

Then in Anaphase II, they start to pull apart as the two sister chromatids that make up a chromosome, now are being ripped apart.

Telophase II is when it splits into four cells, where each cell has one unravelling father and one mother chromosome, then the nuclear envelope forms again, the micro tubulars dissolve.
