Zygote

A zygote ( from Ancient Greekζυγωτός (zygōtós)'joined, yoked', from ζυγοῦν (zygoun)'to join, to yoke') is a eukaryoticcell 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 of a new individual organism.

The sexual fusion of haploid cells is called karyogamy, the result of which is the formation of a diploid cell called the zygote (or zygospore in specific cases).
