During metaphase I , homologous chromosomes randomly line up at the spindle equator. Maternal and paternal chromosomes are shuffled most during metaphase I. Spindle fibers attach to the centromere region of each homologous chromosome pair.
Anaphase I:
During anaphase I, homologous chromosomes (still duplicated) separate and are drawn to opposite poles by the spindle fibers. This results in the formation of two haploid cells, each of which has a random mix of maternal and paternal chromosomes.
Telophase I is similar to Telophase of mitosis, except that only one set of (replicated) chromosomes is in each "cell". Each of the cells formed during Telophase I is haploid.
In prophase II the spindle fibers reform.
Metaphase II is similar to mitosis, with spindles moving chromosomes into the equatorial area and attaching to the opposite sides of the centromeres.
Anaphase II:
During Anaphase II, the centromeres split and the former chromatids (now chromosomes) are segregated into opposite sides of the cell.
Telophase II is similar to Telophase of mitosis. Cytokinesis separates the cells.
