zygote, fertilized ovum(noun)
(genetics) the diploid cell resulting from the union of a haploid spermatozoon and ovum (including the organism that develops from that cell)
A fertilized egg cell.
Origin: From ζυγωτός, from ζυγός.
A zygote, is the initial cell formed when two gamete cells are joined by means of sexual reproduction. In multicellular organisms, it is the earliest developmental stage of the embryo. In single-celled organisms, the zygote divides to produce offspring, usually through Mitosis, the process of cell division. A zygote is always synthesized from the union of two gametes, and constitutes the first stage in a unique organism's development. Zygotes are usually produced by a fertilization event between two haploid cells—an ovum and a sperm cell —which combine to form the single diploid cell. Such zygotes contain DNA derived from both parents, and this provides all the genetic information necessary to form a new individual.
