The phases of Meiosis I in chronological order are:
1. **Prophase I**: Chromosomes condense, and homologous chromosomes pair up in a process called synapsis. Crossing over occurs, exchanging genetic material between homologs.
2. **Metaphase I**: The paired homologous chromosomes align along the equatorial plane of the cell, with spindle fibers attaching to the kinetochores of each homolog.
3. **Anaphase I**: The homologous chromosomes are pulled apart and move towards opposite poles of the cell. Unlike mitosis, sister chromatids remain attached at this stage.
4. **Telophase I**: The chromosomes reach the poles, and the cell begins to divide. In some organisms, the nuclear envelope may reform around the separated sets of chromosomes, followed by cytokinesis, resulting in two haploid cells.
These stages represent the key events in Meiosis I leading to the separation of homologous chromosomes.
