Study Notes
Gametogenesis
- Consists of two main processes: spermatogenesis (formation of sperm) and oogenesis (formation of ova).
- Gametogenesis occurs in the sex cells (gametes).
Spermatogenesis
- Involves three phases: multiplication, growth, and maturation.
- Multiplication Phase: Spermatogonia undergo mitosis to increase their numbers.
- Growth Phase: Spermatogonia differentiate into primary spermatocytes, which then develop into secondary spermatocytes.
- Maturation Phase: Secondary spermatocytes undergo meiosis to produce spermatids.
Oogenesis
- Similar to spermatogenesis but involves the formation of eggs (ova).
Interface Stage
- A prolonged phase of the cell cycle when cells prepare for division without dividing.
- Includes three subphases:
- G1 Phase: Cell growth and organelle duplication.
- S Phase: DNA replication occurs, doubling the genetic material.
- G2 Phase: Continued cell growth and protein synthesis in preparation for division.
Embryonic Development
- Divided into two stages:
- Embryonic Development: Starts at fertilization and continues until birth.
- Post-embryonic Development: Follows birth, encompassing growth until adulthood.
Chromosome Structure
- Composed of chromatin and a centromere, essential for genetic information packaging and segregation during cell division.
