Answer 2

• The process of the formation of the sperm is spermatogenesis.
• This process takes place in testis. The testis in human males is present in the scrotum. The temperature of the scrotum is 2- 2.5 - less than the body temperature.
• Hence, a decrease in temperature does not affect spermatogenesis.
• Spermatogonia are the cells that line the wall of a seminiferous tubule. It gives rise to spermatocytes through mitosis.
• As this is present in the testis, it requires a lower temperature than the average body temperature.
• Hence, both the assertion and the reason are true, but the reason is not the correct explanation for assertion.
