Answer:
The correct answer will be option-False.
Explanation:
Spermatogenesis or formation of sperm cells in humans takes place in two stages: cellular division called "spermatocytogenesis" and metamorphic changes in spermatids to spermatozoa called "Spermiogenesis".
The mitotic and meiotic cellular division produces round spermatids which undergo much physical change during the process called Spermiogenesis. During Spermiogenesis spermatids modify themselves for fertilization like acrosome cap formation, tail development and nuclear condensation.
Thus, option-false is the correct answer.
Only one of the original DNA strands acts as a templates during replication.
