A zygote is the initial cell that forms when two gametes (sperm and egg) fuse during fertilization. It is the starting point of a new organism and contains a complete set of chromosomes, half from the mother and half from the father. The zygote undergoes a series of divisions through the process of mitosis to develop into a multicellular organism.
Key Points to Remember:
The zygote is formed when a sperm cell fertilizes an egg cell.
It contains a complete set of chromosomes, half from the mother and half from the father.
The process of cell division (mitosis) allows the zygote to develop into a multicellular organism.
Genetic information from both parents is combined in the zygote, determining the traits and characteristics of the new organism.
