Question

Match the following columns and select the correct option.

$\begin{array}{cccc}& \text{Column I}& & \text{Column II}\\ a.& \text{Leptotene}& \left(i\right)& \text{Bivalent formation}\\ b.& \text{Zygotene}& \left(ii\right)& \text{Crossing over}\\ c.& \text{Diplotene}& \left(iii\right)& \text{Condensation of chromatin}\\ d.& \text{Pachytene}& \left(iv\right)& \text{Dissolution of synaptonemal}\\ & & & \text{complex}\end{array}$

• A. a(iii), b(i), c(iv), d(ii)
• B. a(ii), b(iii), c(i), d(iv)
• C. a(i), b(iv), c(ii), d(iii)
• D. a(iv), b(i), c(iii), d(ii)

Answer 1

The correct option is A a(iii), b(i), c(iv), d(ii)

● Synaptonemal complex dissolves in diplotene stage.
● In leptotene, condensation of chromatin occurs.
● Crossing over occurs in pachytene.
● Bivalent formation is seen during zygotene.
