Fertilization and Cleavage are two crucial processes that take place during embryonic development. During fertilization, a sperm cell from the male gamete (spermatozoon) and an egg cell from the female gamete (ovum) combine to form a zygote. This zygote then implants itself into the lining of the female's uterus, developing into an embryo.
During cleavage, the zygote divides into smaller and smaller cells, resulting in the formation of a blastocyst. This blastocyst then implants itself into the lining of the female's uterus, establishing a new embryo.
Fertilization and cleavage are essential for the formation of a complete embryo. They ensure that the zygote is properly implanted into the host, and that the embryo develops into a fully formed fetus
