Given below are two statements: Statement I : Chromosomes become gradually visible under light microscope during leptotene stage. Statement II : The beginning of diplotene stage is recognized by dissolution of synaptonemal complex. In the light of the above statements, choose the correct answer from the options given below:
Options
- ABoth Statement I and Statement II are false
- BStatement I is true but Statement II is false
- CStatement I is false but Statement II is true
- DBoth Statement I and Statement II are true
Correct answer
D. Both Statement I and Statement II are true
Step-by-step solution
- During leptotene stage the chromosomes become gradually visible under the light microscope. - The beginning of diplotene is recognised by the dissolution of the synaptonemal complex and the tendency of the recombined homologous chromosomes of the bivalents to separate from each other except at the site of crossover. Thus both statement I and II are correct.
