Text Solution
Verified by ExpertsGametogenesis is the process by which diploid precursor cells undergo meiotic division to become haploid gametes. In males, this process is called spermatogenesis and produce spermatozoa (sperm). In females, this process is called oogenesis and produce ova (eggs).
In spermatogenesis, the spermatids undertake a process of differentiation in order to become functional sperm cells (spermatozoa). Spermatogenesis is initiated at the time of puberty while oogenesis is initiated at the time of embryonic development. In case of spermatogenesis, all the stages of meiosis take place quickly after one another and there is no time lag between them. In the case of oogenesis, meiosis is suspended at the Prophase I stage. Meiosis resumes only once the puberty begins.
