This is followed by the fusion of these gametes inside the female body, a process called fertilization. The fertilized product of this process is termed as a zygote. As zygote divides and travels up to the uterus, it becomes the embryo which gets implanted in the uterine walls. Thus, the correct sequence is gamete formation, fertilization, zygote, embryo.
