Detailed explanation-1: -Fertilization is the process in which gametes (an egg and sperm) fuse to form a zygote. The egg and sperm are haploid, which means they each contain one set of chromosomes; upon fertilization, they will combine their genetic material to form a zygote that is diploid, having two sets of chromosomes.
Detailed explanation-2: -The sperm plasma then fuses with the egg’s plasma membrane and their nuclei fuse, triggering the sperm head to disconnect from its flagellum as the egg travels down the Fallopian tube to reach the uterus. In vitro fertilization (IVF) is a process by which egg cells are fertilized by sperm outside the womb, in vitro.
Detailed explanation-3: -A pronucleus ( pl. pronuclei) is the nucleus of a sperm or egg cell during the process of fertilization. The sperm cell becomes a pronucleus after the sperm enters the ovum, but before the genetic material of the sperm and egg fuse.
