Describe the changes and various phases seen during Meiosis-$II$ with a diagram.

(N/A) Meiosis-$II$ takes place in four sub-phases.
$\Rightarrow$ Meiosis-$II$ resembles a normal mitosis. The behavior of chromosomes is maintained in its sub-phases/stages:
$\Rightarrow$ $(i)$ Prophase-$II$,$(ii)$ Metaphase-$II$,$(iii)$ Anaphase-$II$,and $(iv)$ Telophase-$II$ are seen.
$(i)$ Prophase-$II$: Meiosis-$II$ is initiated immediately after cytokinesis. The nuclear membrane disappears by the end of Prophase-$II$. The chromosomes again become compact.
$(ii)$ Metaphase-$II$: The chromosomes align at the equator,and microtubules from opposite poles of the spindle get attached to the kinetochores of sister chromatids.
$(iii)$ Anaphase-$II$: It begins with the simultaneous splitting of the centromere of each chromosome (which was holding the sister chromatids together),allowing them to move toward the opposite poles of the cell.
$(iv)$ Telophase-$II$: Meiosis ends with Telophase-$II$,in which the two groups of chromosomes once again get enclosed by a nuclear envelope.
$\Rightarrow$ Cytokinesis follows,resulting in the formation of a tetrad of cells,i.e.,four haploid daughter cells.
