Question
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
A.Statement I is true but Statement II is false
B.Statement I is false but Statement II is true
C.Both Statement I and Statement II are true
D.Both Statement I and Statement II are false
Solution
Sol. [Key Concept: Leptotene and diplotene]
Statement I is true: chromosomes progressively condense and become visible during leptotene.
Statement II is true: diplotene begins with dissolution of the synaptonemal complex; homologues start separating but remain associated at chiasmata. Hence, option (3).
