Concept:
Gametogenesis is a fundamental biological process related to reproduction.
Step 1: Definition.
Gametogenesis is the process by which diploid germ cells undergo meiosis and differentiation to form haploid gametes (sperm in males and ova in females).
Step 2: Types.
- Spermatogenesis $\rightarrow$ Formation of sperm in testes
- Oogenesis $\rightarrow$ Formation of ova in ovaries
Step 3: Conclusion.
Thus, gametogenesis ensures the production of reproductive cells necessary for sexual reproduction.
