Gametogenesis → Gamete transfer → Syngamy → Zygote → Cell division (Cleavage) → Cell differentiation → OrganogenesisGametogenesis is the formation of gametes. During gamete transfer, male and female gametes reach fallopian tube where fertilisation (syngamy) takes place resulting in the formation of zygote. The zygote undergoes cleavage producing blastomeres which undergo differentiation and later give rise to various organs (organogenesis).
