  1. Gametogenesis • Gametes develop in the gonads (sex cells)

  2. Their are 2 types ofgametogenesis

  3. Production of sperm in the testes Produce 4 sperm from one cell Meiosis Spermatogenesis

  4. Male Reproductive System

  5. Production of eggs in the ovary. Produce 4 eggs by meiosis One egg cells is function Three egg cells are nonfunctional The are known as polar bodies Oogenesis

  6. Female Reproductive System Lastly the sperm and egg meet here for fertilization Sperm must pass through the uterus 2nd Sperm Enters the vagina 1st

  7. OviductFertilization occurs here

  8. Zygote is a fertilized egg. A fertilized egg becomes an embryo as soon as the first cleavage occurs. Zygote

  9. Chance of zygote survival is increased greatly Internal Ferilization

  10. Zygotes chance of survival decreases significantly External Fertilization
