The complex formed by a pair of synapsed homologous chromosomes is called

Match the stages of prophase $I$ given in Column-$I$ with their features in Column-$II$ and choose the correct options from the choices given below:

Column $I$	Column $II$
$A$. Leptotene	$i$. Chromosomes visible under light microscope
$B$. Zygotene	$ii$. Chromosomes start pairing together
$C$. Pachytene	$iii$. Exchange of genetic materials between non-sister chromatids of the homologous chromosomes.
$D$. Diplotene	$iv$. Dissolution of synaptonemal complex
$E$. Diakinesis	$v$. Terminalisation of chiasmata

Synapsis occurs during the ....... stage of meiosis.

If a leaf cell has $8$ chromosomes,it is most likely that:

Match the following stages of meiosis with their respective events:

List-$I$	List-$II$
$a$. Zygotene	$i$. Terminalization
$b$. Pachytene	$ii$. Chiasmata
$c$. Diplotene	$iii$. Crossing over
$d$. Diakinesis	$iv$. Synapsis

Select the correct option: $a \quad b \quad c \quad d$

The genetic constitution of chromosomes changes after this type of cell division.
