... cell divides mitoticaly and equally to form 2 primary spermatocyres and then these undergo unequal cytoplasmic division of Mitosis to form 2 spermatids and 2 Polar bodies. According to some investigators, polar bodies get disappeared. So haploid male gives rise to haploid gametes and diploid ...

Cell identification - germ cells in haploid male ants

... somehow. In the female ant, I assume the specie's genes instruct standard meiosis to be used. Germ cells are modified two times before they become spermatids. The spermatids go through a maturation process before becoming sperm cells (gametes), at least in some organisms. http://www.biology-questions-and-answers.com/gametogenesis.html ...

Gamete Formation Definition?

... These primary spermatocytes undergo MEIOSIS to form a pair of secondary spermatocytes, and these undergo meiosis II to form a quadruplet of spermatids. So technically each spermatogonium can form an infinite number of spermatids.

Gamete Formation Definition?

... 2 primary spermatocytes 2 primary spermatocytes -->(meiosis I) 4 secondary spermatocytes 4 secondary spermatocytes --> (meiosis II) 8 spermatids development.... --> 8 sperm I'm confused at this inconsistency. Technically, if one spermatogonium undergoes mitosis to form 2 primary ...
