== Gamete vs. Zygote ==

In sexual reproduction, a gamete is a reproductive cell that unites with another gamete to form a zygote.<ref name="ref1" /><ref name="ref2" /> Gametes are haploid, meaning they contain a single set of chromosomes.<ref name="ref3" /><ref name="ref4" /> A zygote, on the other hand, is the diploid cell that results from the fusion of two haploid gametes, a process known as fertilization.<ref name="ref5" /> The zygote contains a complete set of chromosomes, with half contributed from each gamete.

Female gametes are known as ova or egg cells, while male gametes are called sperm.<ref name="ref3" /> Ova are typically non-motile and larger than the motile sperm cells. The fusion of an egg and sperm creates the single-celled zygote, which represents the first stage of development for a new organism. This initial cell carries all the genetic information necessary for the development of a genetically unique individual.

The formation of gametes occurs through a process of cell division called meiosis, which reduces the number of chromosomes in a diploid parent cell by half to produce haploid cells.<ref name="ref4" /> In contrast, after fertilization, the zygote undergoes a series of cell divisions through mitosis, where the diploid chromosome number is maintained in each new cell, leading to the development of an embryo.<ref name="ref1" />

In humans, gametes each contain 23 chromosomes. Upon fertilization, they combine to form a zygote with 46 chromosomes. The zygote stage is brief, lasting only a few days before it begins to divide and develop into a blastocyst, and subsequently an embryo.
