Prophase II- Nuclear envelopes break down, spindle fibers form. The process is occuring in the two new cells now.
Metaphase II-spindle fibers move chromosomes to equator.
Anaphase II-spindle fibers pull sister chromatids apart.
Telophase II- nuclear envelopes form, spindle fibers break down. Cytokinesis results in four daughter cells with one set of chromatids=four haploid cells (haploid gametes) these would be sperm or eggs in humans.
