Prophase I is divided into 5 distinctive sub-stages:
●Leptotene – The chromosomes begin to condense and are attached to the nuclear membrane via their telomeres
●Zygotene – Synapsis begins with a synaptonemal complex forming between homologous chromosomes
●Pachytene – Crossing over of genetic material occurs between non-sister chromatids
●Diplotene – Synapsis ends with disappearance of synaptonemal complex; homologous pairs remain attached at chiasmata
●Diakinesis – Chromosomes become fully condensed and nuclear membrane disintegrates prior to metaphase I
●Leptotene – The chromosomes begin to condense and are attached to the nuclear membrane via their telomeres
