Edouard van beneden proposed that an egg and a sperm, each containing half the complement of chromosomes found in somatic cells, fuse to produce a single cell called a zygote.
Zygote
A zygote (from the Ancient Greek zygtós, "joined, yoked," from v (zygoun), "to join, to yoke") is a fertilized egg. [1] is an example of a eukaryotic cell produced by the fertilization of two gametes. The genome of the zygote, which is made up of the DNA from each gamete, has all of the genetic material for a brand-new unique organism.
The zygote represents the earliest developmental stage of multicellular organisms. A zygote is produced when an egg cell and sperm cell combine to form a new, distinct organism, as is the case in humans and the majority of other anisogamous organisms. The zygote can split asexually through mitosis in single-celled organisms to create identical progeny.
