How many secondary spermatocytes will be required to form 400 spermatozoa?
Open in App
Solution
The correct option is B 200
One primary spermatocyte produces two secondary spermatocytes through meiosis 1. Each secondary spermatocyte produces two spermatids through meiosis 2. Each spermatid produces one spermatozoa.
Hence, to get 400 spermatozoa, 200 secondary spermatocytes are required.
So, the correct answer is '200'
