Answer:

Meiosis is a process where a cell divides twice to produce four daughter cells, each containing half the original amount of genetic information of the parent cell. The process begins with a parent cell that is diploid (2n), meaning it has two sets of chromosomes, one from each parent.

Here's a brief explanation of the stages:

1. Interphase: The parent cell undergoes DNA replication, resulting in chromosomes that consist of two sister chromatids.

2. Meiosis I:

  • Prophase I: Homologous chromosomes pair up and exchange genetic material through crossing over.

  • Metaphase I: Paired homologous chromosomes line up at the cell's equator.

  • Anaphase I: Homologous chromosomes are separated and pulled to opposite poles of the cell.

  • Telophase I and Cytokinesis: The cell divides into two haploid (n) daughter cells, each containing half the number of chromosomes, but each chromosome still consists of two sister chromatids.

3. Meiosis II:

  • Prophase II: The two haploid cells prepare for a second division.

  • Metaphase II: Chromosomes line up at the equator of each haploid cell.

  • Anaphase II: Sister chromatids are finally separated and pulled to opposite poles.

  • Telophase II and Cytokinesis: Each of the two haploid cells divides again, resulting in four haploid daughter cells.
