Zygote

n. any cell formed by the union of male and female gametes; fertilized egg; embryo at beginning of cell division (Biology)

For other meanings see Zygote (disambiguation). A zygote (Greek: ζυγωτόν) is a cell that is the result of fertilization. That is, two haploid cells—usually (but not always) an  ovum from a female and a sperm cell from a male—merge into a single  diploid cell called the zygote (or zygocyte).Animal zygotes undergo mitotic cell divisions to become an embryo. Other organisms may undergo meiotic cell division at this time (for more information refer to biological life cycles).
