Study Notes
Spermatogenesis
- The process of sperm cell formation
- Begins with a diploid spermatogonium (46 chromosomes)
- Spermatogonium undergoes mitosis to produce a primary spermatocyte (46 chromosomes)
- Primary spermatocyte undergoes meiosis I, producing two secondary spermatocytes (23 chromosomes)
- Secondary spermatocytes undergo meiosis II, producing two spermatids (23 chromosomes)
- Spermatids differentiate into mature sperm cells (23 chromosomes)
- The process is depicted in a flow chart diagram
- Spermatogonium, primary spermatocyte, and secondary spermatocyte are represented as purple circles
- Each circle is labeled with its corresponding chromosome number (2n or n)
- Dashed lines separate different stages
- Circular arrows in the diagram represent the transformation process between stages
