Study Notes
Reproductive System Interaction
- During sexual intercourse, the male and female reproductive systems interact, resulting in the fusion of gamete cells.
Gamete Cells
- Gamete cells, namely sperm and egg cells, have a unique genetic composition: haploid, with 23 chromosomes.
Zygote Formation
- The merger of the male and female gamete cells results in a single cell called a zygote, which is diploid, containing 46 chromosomes.
Embryonic Development
- After the formation of the zygote, the defined development process is called embryogenesis, which involves several stages: cleavage, gastrulation, and organogenesis.
Fertilization Mechanism
- The fertilization of the ovum (egg cell) is achieved when a spermatozoon penetrates the ovum, resulting in the fusion of their genetic material.
