Question

List the sub-stages of prophase-I.

Answer 1

Dear Student,

● Prophase-I -

• It is longest and most complex phase of meiosis.
• Chromosomes condense in this phase.
• Homologous chromosomes synapse to form a tetrad.
• Here, non-sister chromatids exchange genetic material called as crossing over.

# Prophase of meiosis-I is subdivided into 5 stages -

1. Leptotene
2. Zygotene
3. Pachytene
4. Diplotene
5. Diakinesis

Hope this helped you. Thanks for asking..

Answer 2

Sub-stages of prophase-I:

• Prophase-I is the first stage of the meiosis cell division. This is the most complicated stage of the meiosis cell division. Prophase-I has various sub-stages like Leptotene, Zygotene, Pachytene, Diplotene, and Diakinesis in this order.
• This is the longest phase than the other phases of the meiosis cell division. In the Prophase-I phase, the chromosomes became visible, condensed, shorter, thicker, coiled and duplicated and can be visible properly under the microscope.
