Question

In onion root tip during metaphase stage of mitosis the number of kinetochores will be

• A. $4$
• B. $8$
• C. $16$
• D. $32$

Answer 1

The correct option is D $32$

2n = 16

In onion root tips, during the metaphase stage of mitosis, the number of kinetochores will be 32. This is because one chromosome contains 2 kinetochores.

Therefore, the number of kinetochore = 2 × number of chromosomes(16).

So the correct option is "32".
