Sr.no	List I	Sr.no	List II
A.	Synaptonemal complex	1.	Pachytene
B.	Recombination nodule	2.	Zygotene
C.	Terminalisation of chiasmata	3.	Telophase I
D.	Formation of dyad cell	4.	Diakinesis

• A. A-(ii),B-(i),C-(iv),D-(iii)
• B. A-(i),B-(ii),C-(iv),D-(iii)
• C. A-(iii),B-(i),C-(iv),D-(ii)
• D. A-(ii),B-(i),C-(iii),D-(iv)

Answer 1

The correct option is A A-(ii),B-(i),C-(iv),D-(iii)

Meiosis has the prophase stage which is the longest phase of karyokinesis otherwise. It is then divided into five different phases.

• Leptotene is the phase where the chromosomes are present as a long thread with chromosomes on it.
• Zygotene is the second stage where the pairing of synopsis of homologous chromosomes takes place here.
• Pachytene is the stage where the crossing over or exchange of segments between non-sister chromatids of homologous chromosomes takes place.
• Diplotene is the stage where the chromosome begins to separate and terminalization starts.
• Diakinesis is the stage where the nuclear membrane starts degeneration.

Thus, the correct answer is 'A-(ii), B-(i), C-(iv), D-(iii).'
