Question 28 of 34

🟢 NEET 2024 📘 CLASS XI

Given below are two Statements:
Statement I: Chromomes become gradually visible under light microscope during leptotene stage.
Statement II: The begining 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:

Explanation:

Statement I is true: chromosomes begin to condense during leptotene and become visible under light microscopy as threads. Statement II is false according to NCERT: the dissolution of the synaptonemal complex begins after the zygotene stage and is not used to define the onset of diplotene as per NCERT wording. Hence, the correct option is 4.

🧠 Did You Know?

In diplotene, chiasmata become visible as homologous chromosomes start to separate while remaining joined at crossover points.

💡 NCERT Memory Line:

Leptotene: chromosomes first condense; Diplotene: desynapsis begins with synaptonemal complex dissolution not used to mark diplotene onset in NCERT phrasing.
