Describe the changes and various phase seen during Meiosis - II with diagram.

Explanation

Meiosis II takes place in four sub phase.
Meiosis II resembles a normal mitosis. The nuclear of chromosomes is maintained in its sub phase / stages :
(i) Prophase - II (ii) Metaphase - II (iii) Anaphase - II (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 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 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. Cytokinesis follows resulting in the formation of tetrad of cells i.e., four haploid daughter cells.
