Fertilization of an egg happens before it is laid.
in the egg cell after fertilization...or after fertilization and before birth
Sperm have about three days to make it to the egg for fertilization before the egg passes out of the uterus and dies.
The female egg splits only once during fertilization. This split occurs after the egg is fertilized by a sperm, resulting in the formation of a zygote that will develop into an embryo.
Before fertilization in embryology, the egg and sperm undergo a process called gametogenesis where they mature, and then they are released from the ovaries and testes. Once released, they meet during fertilization to form a zygote.
Fertilization
After fertilization while the egg is developing into an embryo, a cell may split off and form a separate fetus.
The process of uniting an egg with a sperm is called fertilization. It occurs when a sperm cell penetrates the outer layer of an egg cell and fuses with the egg's nucleus, forming a zygote. This marks the beginning of a new organism's development.
