[edit] ploidy
I put this on the spermatogenesis page too, and im pretty sure the chromosmal orientation in primary spermatocytes and secondary spermatocytes is incorrect as discussed in this topic. This is how I understand it, and I have some literature that also infers what I am saying.
Spermatogonia (2N)
(Mitosis)
Primary Spermatocytes (4N)
(Meiosis 1)
Secondary Spermatocytes (2N)
(Meiosis 2)
Spermatid & beyond (N)
This may look crazy at first but it makes way more sense. How can you go through meiosis 2 without halving the chromosome count?? This always perplexed me until i looked into it furhter and found literature on the subject. Here it is:
1)Kimura, Y. (1995). Development of Normal Mice from Oocytes Injected with Secondary Spermatocyte Nuclei (in: BIOLOGY OF REPRODUCTION 53, 855-862)
2)Ogura, A. (1998). Development of Normal Mice from Metaphase I Oocytes Fertilized with Primary Spermatocytes (in: Proceedings of the National Academy of Sciences, Vol. 95, No. 10 pp. 5611-5615)(first paragraph of abstract)
3)Mays-Hoopes, L.L. (1995). Preparation of Spermatogonia, Spermatocytes, and Round Spermatids for Analysis of Gene Expression Using Fluorescence-Activated Cell Sorting. (in: BIOLOGY OF REPRODUCTION 53, 1003-1011)
4)This website lays it out pretty clear http://www.expertreviews.org/01002320h.htm
Hope someone can address this...maybe i will if i dont get murdered Jimboapu (talk) 04:02, 25 April 2008 (UTC)
