Meiosis II known as the duplicative phase, resembles mitosis: two whole individuals are formed by duplicating DNA, its phases are as follows:
- Prophase II - Centromeres move toward the poles of the cell ..
The haploid cells created in meiosis I condense their chromosomes and break the nuclear envelope, the achromatic spindle appears again.
- Metafase II - Chromosomes are lined up by spindle fibers.
As before, the chromosomes tend towards the equatorial plane of the cell, preparing for a new division.
- Anaphase II - Sister chromatids are pulled apart.
The sister chromatids of each chromosome separate and are pulled toward opposite poles of the cell.
- Telophase II - Nuclear envelope forms around each set of DNA.
The nuclear envelope is formed again, followed by the partition of the cytoplasm and the formation of cell membranes resulting in four haploid cells, each with a different distribution of the complete genetic code of the individual.
Therefore, we can conclude that meiosis II is a cell division process through which two whole individuals are formed by duplicating DNA.
