Q152 / 180 · NEET 2020 (Phase 2) · Zoology

Select the correct option of haploid cells from the following groups:

  • A
    Primary oocyte, Secondary oocyte, Spermatid
  • Correct answer
    B
    Secondary spermatocyte, First polar body, Ovum
  • C
    Spermatogonia, Primary spermatocyte, Spermatid
  • D
    Primary spermatocyte, Secondary spermatocyte, Second polar body

Solution

During spermatogenesis and oogenesis, various structures are formed that are either haploid or diploid in nature. Based on ploidy, the structures can be classified as:

Diploid (2n): Spermatogonia, primary spermatocyte, oogonia, and primary oocyte.

Haploid (n): Secondary spermatocyte, spermatids, spermatozoa, polar bodies, secondary oocyte, and ovum.

Hence, the correct answer is option: 'B'.
