Meiosis I

The first meiotic division involves the separation of homologous chromosomes. This does not occur in mitosis.

Prophase I Condensed homologous chromosomes cross over, i.e. swap equivalent sections of DNA. This occurs at a point called the chiasmata, which is where chromosomes form an intersection. New alleles form through this process.
Metaphase I The chromosomes now align along the equator of the cell. Spindles attach to their centromeres.
Anaphase I The pairs of chromosomes are now pulled to the poles of the cell.
Telophase I There is now a haploid set of chromosomes at each end of the cell, but each chromosome still contains two chromatids.
Cytokinesis This occurs after telophase I, forming two daughter cells
