Final answer:
Gametogenesis is the process where haploid gametes are produced through meiosis, involving meiotic division, growth, maturation, and differentiation. In spermatogenesis, sperm cells are formed, while in oogenesis, a mature ovum is developed.
Step-by-step explanation:
Gametogenesis Stages
Gametogenesis is the biological process where haploid gametes are produced in the reproductive organs through meiosis. The four general stages of gametogenesis include:
- Meiotic Division: Cells undergo meiosis I and meiosis II to reduce the chromosome number by half and produce four haploid cells.
- Growth Phase: These haploid cells grow and undergo cellular changes. In males, this stage leads to the formation of spermatids.
- Maturation: The gametes mature; spermatids develop into spermatozoa, and oocytes complete their development into mature ovum.
- Differentiation: Gametes acquire distinct features like flagella in sperm or nutrient reserves in eggs.
In males, this process is known as spermatogenesis and results in the formation of sperm cells. In females, the process is called oogenesis, and it results in the development of a mature ovum.
