Question

explain the five stages of prophase 1 of meiosis​

Answer 1

Answer:

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
