Meiosis is the process of creating haploid gametes from a diploid cell.

If everything goes smoothing during meiosis, chromosomes will be separated and distributed evenly to produce four haploid gametes.

Both the cells produced in meiosis I undergo meiosis II.

During this round, chromosomes line up and sister chromatids are pulled apart into two sets. The pulling apart of either homologous chromosomes or sister chromatids is called disjunction and occurs during anaphase of meiosis I or meiosis II, respectively.

The end result is two cells that have an extra copy of one chromosome and two cells that are missing that chromosome.

In humans, n 1 designates a cell with 23 chromosomes plus an extra copy of one for a total of 24 chromosomes.

To get ready for meiosis, a diploid germ cell must first undergo DNA replication.

In this example, one cell with 5 chromosomes and one cell with 3 chromosomes are produced.

Each cell undergoes meiosis II, resulting in two cells with n 1, or 5, and two cells with n - 1, or 3.

Once DNA replication is complete, two rounds of chromosomal divisions take place, one each in meiosis I and meiosis II.

During meiosis I, homologous chromosomes pair up, line up, and then are split apart.
