Given below are two statements: Statement I: A primary spermatocyte completes the first meiotic division leading to the formation of two equal, haploid cells called secondary spermatocytes. Statement II: The secondary spermatocytes possess 46 chromosomes each and undergo the second meiotic division to produce spermatids. In the light of the above statements, choose the most appropriate answer from the options given b

Options

  1. ABoth Statement I and Statement II are incorrect
  2. BStatement I is correct but Statement II is incorrect
  3. CStatement I is incorrect but Statement II is correct
  4. DBoth Statement I and Statement II are correct

Correct answer

B. Statement I is correct but Statement II is incorrect

Step-by-step solution

Statement I is correct. During spermatogenesis, a primary spermatocyte (diploid, 2n=46 ) undergoes the first meiotic division (reductional division) to form two equal, haploid cells known as secondary spermatocytes. Statement II is incorrect. Since the first meiotic division is a reductional division, the resulting secondary spermatocytes are haploid and possess only 23 chromosomes each, not 46 . These secondary spermatocytes then undergo the second meiotic division to produce four equal, haploid spermatids. Answer
