The goal of the Defense Threat Reduction Agency is to reduce the threat of Weapons of Mass Destruction (WMD) to the United States by either eliminating foreign stockpiles or mitigating their risk to the U.S. and its allies.
Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, and the two secondary spermatocytes by their subdivision produce four spermatozoa. Spermatozoa are the mature male gametes in many sexually reproducing organisms.Thus, spermatogenesis is the male version of gametogenesis. In mammals it occurs in the seminiferous tubules of the male testes in a stepwise fashion.aturation occurs in the epididymis. The location [Testes/Scrotum] is specifically important as the process of spermatogenesis requires a lower temperature to produce viable sperm, specifically 1Â°-8 Â°C lower than normal body temperature of 37 Â°C (98.6 Â°F).
Meiosis. Spermatogenesis is the process by which the male gametes, called sperm, are created. Now, you may recall that in order to create sperm that can combine with a female gamete, each sperm must be haploid and contain only one copy of each chromosome.eiosis.
