A zygote (from Greek Î¶ÏÎ³ÏÏÏÏ zygÅtos joined or yoked, from Î¶ÏÎ³Î¿á¿¦Î½ zygoun to join or to yoke), is a eukaryotic cell formed by a fertilization event between two gametes. The zygote's genome is a combination of the DNA in each gamete, and contains all of the genetic information necessary to form a new individual.In multicellular organisms, the zygote is the earliest developmental stage.n human fertilization, two 1n haploid cellsâan ovum (female gamete) and a sperm cell (male gamete)âcombine to form a single 2n diploid cell called the zygote.
The zygote's genome is a combination of the DNA in each gamete, and contains all of the genetic information necessary to form a new individual.In multicellular organisms, the zygote is the earliest developmental stage.n plants, the zygote may be polyploid if fertilization occurs between meiotically unreduced gametes. In land plants, the zygote is formed within a chamber called the archegonium. In seedless plants, the archegonium is usually flask-shaped, with a long hollow neck through which the sperm cell enters.
