Select the correct sequence of events.

1. Gametogenesis → Gamete transfer → Syngamy → Zygote → Cell differentiation → Cell division (Cleavage) → Organogenesis.
2. Gametogenesis → Gamete transfer → Syngamy → Zygote → Cell division (Cleavage) → Cell differentiation → Organogenesis.
3. Gametogenesis → Gamete transfer → Syngamy → Zygote → Cell division (Cleavage) → Organogenesis → Cell differentiation.
4. Gametogenesis → Syngamy → Gamete transfer → Zygote → Cell division (Cleavage) → Cell differentiation → Organogenesis.

Correct answer: Gametogenesis → Gamete transfer → Syngamy → Zygote → Cell division (Cleavage) → Cell differentiation → Organogenesis.

Solution

The correct order follows the normal sequence of sexual reproduction and early embryonic development: gametes are formed, transferred, and fuse during syngamy to make a zygote. The zygote then undergoes cleavage, followed by cell differentiation and organogenesis.
