Which of the following cells during gametogenesis is normally dipoid?

  • Primary polar body

  • Spermatid

  • Spermatogonia

  • Secondary polar body

Solution

C.

Spermatogonia

Spermatogonium are produced from the undifferentiated primordial germ cells which divide continuously by mitosis to form diploid cells, i.e. primary spermatocyte. These are the precursors of sperms, (the haploid cells). Primary polar body, secondary polar body (in oogenesis) are produced after first meiotic division as haploid cells. Spermatids are haploid cells produced by second meiotic division of secondary spermatocytes (n).
