How many spermatozoa will be produced from 150 primary spermatocytes?

Options

  1. A150
  2. B75
  3. C300
  4. D600

Correct answer

D. 600

Step-by-step solution

In spermatogenesis, each primary spermatocyte undergoes the first meiotic division (Meiosis I) to form two secondary spermatocytes. Each secondary spermatocyte then undergoes the second meiotic division (Meiosis II) to form two spermatids. Thus, one primary spermatocyte ultimately yields four haploid spermatids, which differentiate into four spermatozoa. Therefore, 150 primary spermatocytes will produce 150 4 = 600 spermatozoa. Answer: 600
