Recall that meiosis I is the first division in meiosis, where homologous chromosomes are separated. It consists of four main phases: Prophase I, Metaphase I, Anaphase I, and Telophase I.
Understand the sequence of events: Prophase I is when homologous chromosomes pair up and crossing over occurs; this is the longest and earliest phase.
Next, in Metaphase I, the paired homologous chromosomes align along the metaphase plate in the center of the cell.
Then, during Anaphase I, the homologous chromosomes are pulled apart to opposite poles of the cell, but sister chromatids remain together.
Finally, Telophase I is when the chromosomes arrive at the poles, and the cell divides into two haploid cells, completing meiosis I.
