Q. Arrange the following events of meiosis I in the correct order:
(i) Diplotene
(ii) Pachytene
(iii) Zygotene
(iv) Diakinesis
(v) Leptotene

1. (i); (ii); (iii); (iv); (v)
2. (v); (iii); (ii); (i); (iv)
3. (i); (iii); (ii); (v); (iv)
4. (ii); (iii); (i); (v); (iv)

Q. Match the following:

$\begin{array}{cccc}& \text{Column A}& & \text{Column B}\\ \text{A}& \text{Diplotene}& \text{i}& \text{Appearance of recombination nodule and recombination between homologous chromosomes}\\ \text{B}& \text{Diakinesis}& \text{ii}& \text{Dissolution of the synaptonemal complex and formation of the chiasmata}\\ \text{C}& \text{Zygotene}& \text{iii}& \text{Compaction of chromosomes}\\ \text{D}& \text{Pachytene}& \text{iv}& \text{Terminalisation of the chiasmata}\\ \text{E}& \text{Leptotene}& \text{v}& \text{Synapsis and formation of the bivalent}\end{array}$

1. A-ii; B-iv; C-v; D-i; E-iii
2. A-ii; B-v; C-iv; D-iii; E-i
3. A-i; B-iv; C-iii; D-ii; E-v
4. A-v; B-iv; C-i; D-ii; E-iii

Q. Match the following:

$\begin{array}{cccc}& \text{Column A}& & \text{Column B}\\ \text{A}& \text{Diplotene}& \text{i}& \text{Appearance of recombination nodule and recombination between homologous chromosomes}\\ \text{B}& \text{Diakinesis}& \text{ii}& \text{Dissolution of the synaptonemal complex and formation of the chiasmata}\\ \text{C}& \text{Zygotene}& \text{iii}& \text{Compaction of chromosomes}\\ \text{D}& \text{Pachytene}& \text{iv}& \text{Terminalisation of the chiasmata}\\ \text{E}& \text{Leptotene}& \text{v}& \text{Synapsis and formation of the bivalent}\end{array}$

1. A-ii; B-iv; C-v; D-i; E-iii

Q.

Match the substages of prophase I of first meiotic division listed in column I with the important events pertaining to respective stages given under column II; choose the answer which gives the correct combination of alphabets of the two columns:

$\begin{array}{cccc}& ColumnISubstagesofprophaseI& & ColumnIIImportantevents\\ A& \text{Zygotene}& p& \text{Chromomeres}\\ B& \text{Pachytene}& q& \text{Bivalents migrate to periphery}\\ C& \text{Diplotene}& r& \text{Terminalization of chiasmata begins}\\ D& \text{Diakinesis}& s& \text{Crossing over}\\ & & t& \text{Synapsis}\end{array}$

1. A = t, B = s, C = r, D = q

2. A = p, B = s, C = r, D = q

3. A = s, B = p, C = r, D = q

4. A = s, B = t, C = r, D = q
