Embryogenesis
1. Formation of Zygote
The zygote is formed after fertilization, which is the fusion of the sperm and ovum.
It is a single diploid cell containing 46 chromosomes.
The zygote represents the first stage of human development.
, 2. Cleavage (Cell Division)
After formation, the zygote undergoes rapid mitotic divisions known as cleavage.
The sequence of division is as follows:
2-cell stage → 4-cell stage → 8-cell stage
