An organism has two pair of chromosomes(i.e. chromosome number=4). Diagrammatically represent the chromosome arrangement during different phases of meiosis II.

Dear student,
Please find below the solution to the asked query

The diagramatic representation of meiosis II for the organism having two pairs of chromosomes is as under:

Meiosis II − Resembles Mitosis

  • Prophase II − Chromosomes become compact and nuclear membrane disappears.

  • Metaphase II − Chromosomes align on equatorial plate and spindle fibres appear and attach to kinetochores of sister chromatids.

  • Anaphase II − Centromere of each chromosome splits and sister chromatids move towards opposite poles of the cell.

  • Telophase II − Nuclear envelope reappears and cytokinesis follows, resulting in formation of a tetrad (4 haploid cells).

Hope this information will clear your doubts about the meiosis II.
