What is the cell called that results from the fertilization of a gamete?

The cell that results from the fertilization of a gamete is called a zygote. When a sperm cell, which is a male gamete, unites with an egg cell, the female gamete, they form the zygote. This zygote represents the first stage of development for a new organism, containing a full set of chromosomes derived from both parents. As the zygote undergoes cell division and development, it eventually forms an embryo, but at this initial stage, it is specifically referred to as a zygote. Understanding this terminology is crucial in genetics and developmental biology, as it marks the beginning of the organism's life cycle.
