Identify the correct sequence of events during Prophase I of meiosis: (a) Synapsis of homologous chromosomes (b) Chromosomes become gradually visible under microscope (c) Crossing over between non-sister chromatids of homologous chromosomes (d) Terminalisation of chiasmata (e) Dissolution of synaptonemal complex Choose the correct answer from the options given below :

Options

  1. A(a), (b), (c), (d), (e)
  2. B(b), (c), (d), (e), (a)
  3. C(b), (a), (c), (e), (d)
  4. D(a), (c), (d), (e), (b)

Correct answer

C. (b), (a), (c), (e), (d)

Step-by-step solution

The order of events during prophase I of Meiosis-I is as follows: Leptotene →\rightarrow Thickening of chromosome Zygotene →\rightarrow Synapsis of chromosome Pachytene →\rightarrow Crossing over Diplotene →\rightarrow Dissolution of synaptonemal complex Diakinesis →\rightarrow Terminalisation of chiasmata.
