Embryogenesis is the main event in post fertilization.Here, development of embryo from the diploid zygote is known as embryogenesis.

Embryonic development starts with the fertilization of an egg cell (ovum) by a sperm cell, (spermatozoon).Once fertilized, the ovum becomes a single diploid cell known as a zygote. The zygote undergoes mitotic divisions with no significant growth (a process known as cleavage) and cellular differentiation, leading to development of a multicellular embryo.after passing through an organizational checkpoint during mid-embryogenesis.In mammals, the term refers chiefly to the early stages of prenatal development, whereas the terms fetus and fetal development describe later stages.
