2n16 in a primary spermatocyte which is in metaphase of first meiotic division. What shall be the total number of chromatids in each of the secondary spermatocyte?
- A 16
- B 24
- C 32
- D 8
Answer & Solution
Correct Answer
(A) 16
Step-by-step Solution
Detailed explanation
(A) 16,
During the first meiotic division, a primary spermatocyte (2n=16) produces secondary spermatocytes, each with 8 chromosome (haploid). Since each chromosome has 2 chromatids, the total number of chromatids in each secondary spermatocyte is 16.
