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.
