Study Notes
Reproductive System Interaction
- During sexual intercourse, the male and female reproductive systems interact to produce a fertilized zygote.
Gamete Cells
- Gamete cells have a chromosome count of 23 (haploid).
Fertilization
- The process of two gamete cells merging into one zygote cell is called fertilization.
Development Process
- The defined development process that the zygote undergoes is embryogenesis.
Gestation Period
- The typical gestation period for a human offspring is approximately 38 weeks (or 266-270 days).
