In prophase II, there is no chromosome duplication (chromosome replication), like what happens in meiosis I. In this phase, there occurs duplication in centrioles which produces daughter centrioles with perpendicular position of the parent centrioles are then separated into two centrosomes . Nucleus membrane disappears, and spindle is formed.
Meiosis II and its stages. At the end sister chromatid separate and produce 4 daughter
cell (haploid) containing single chromosome.
In this phase, each daughter cell has finished forming spindle. Each Chromosomes arranges themselves by lining up in metaphase plate, just Like what happens in mitosis. Each chromatid kinetochore points to Opposite pole, and spindle that comes from each pole attaches to each Kinetochore.
In this phase, centromere in each chromosome is separated and two Chromatids from each chromosome move to opposite pole. The separated Chromatid now functions as chromosome for each daughter cell.
In this phase, nucleus membrane is formed and surrounds each set of Chromosomes followed by cytokinesis. This process produces 4 daughter cells each of which contains one set of haploid chromosomes (z).
Meiosis occurs in reproduction organ by producing haploid (n) sex cells. Meiosis that produces sex cells (gamete) is called gametogenesis.
