Question

Match the following:

	Column I		Column II
A	Leptotene	1	Terminalisation of chiasmata
B	Zygotene	2	Dissolution of the synaptonemal complex
C	Pachytene	3	Crossing over takes place
D	Diplotene	4	Formation of synaptonemal complex
E	Diakinesis	5	Condensation of chromosome

• A. A-1, B-2, C-3, D-4, E-5
• B. A-4, B-2, C-3, D-5, E-1
• C. A-5, B-2, C-3, D-4, E-1
• D. A-5, B-4, C-3, D-2, E-1

Answer 1

The correct option is D A-5, B-4, C-3, D-2, E-1

Prophase I of meiosis I is divided into five phases:

• Leptotene - This stage is characterised by the condensation of chromosome.
• Zygotene - It is accompanied by the formation of complex structure called synaptonemal complex.
• Pachytene - This stage is characterised by the crossing over event.
• Diplotene - It is recognised by the dissolution of the
  synaptonemal complex.
• Diakinesis - This is marked by terminalisation of chiasmata.
