Question

charismatic formation takes place during stage of prophase II​

Answer 1

Required Answer:-

- Chiasmata formation takes place during Diplotene of Prophase II (a phase of meoisis II).

In this stage,

• The synaptonemal complex is dissolved.
• The recombined homologous chromosomes bof the bivalents have the tendency to separate except at the crossovers.
• And the X shaped structure formed is known as Chiasmata.
• Additional: In some vertebrates, Diplotene plhase of some oocytes can last upto a long time i.e. months and years$.$
• Diplotene is the 4th stage of prophase II.

Answer 2

Answer:

REQUIRED ANSWER:

The chiasmata formation occurs during diplotene phase of prophase I of meiosis.

About:

• During prophase II, chromosomes condense and the nuclear envelope breaks down, if needed.
• The centrosomes move apart, the spindle forms between them, and the spindle microtubules begin to capture chromosomes.
• It leads to an exchange of segments and creates variation.
