During the leptotene stage the chromatin arranges into long and thin strands and at zygotene stage the synapsis of homologous chromosomes takes place, facilitated by assembly of central elements of the synaptonemal complex.

Meiosis involves two rounds of chromosome segregation and thus undergoes prophase twice, resulting in prophase I and prophase II. Prophase I is the most complex phase in all of meiosis because homologous chromosomes must pair and exchange genetic information. Prophase II is very similar to mitotic prophase.
