Explain meiosis-ll in an animal cell

All these happen in the two haploid nuclei simultaneously.
(i) Prophase-II, takes short time. Spindle formation begins and the chromosomes become short. Two chromatids are joined to a single centromere. Nuclear membrane and nucleolus disintegrate.
(ii) Metaphase-II At the equator, the chromosomes lie and spindle is formed. The centromere of every chromosome is joined to the spindle fibre and centromere also divides.
(iii) Anapbase-II The daughter chromosomes are formed. Chromatids move towards their . poles with the spindle fibres.
(iv) Telophase-II Reaching at the poles, chromosomes form nuclei which are haploid (n)
daughter nuclei. Again nuclear membrane is constructed. Nucleolus now becomes clearly visible.
Cytokinesis Occurs and four daughter cells are formed which are haploid (n). It may occur once or twice (i.e., in meiosis-I and n) or only after the meiosis-II cell division.
