Translationszygote
zygote: see reproductionreproduction,
capacity of all living systems to give rise to new systems similar to themselves. The term reproduction may refer to this power of self-duplication of a single cell or a multicellular animal or plant organism.

As distinct from gametes, a zygote has a diploid (double) set of chromosomes. The zygote develops directly after fertilization or, as in many algae and fungi, takes on a thick covering and becomes a dormant spore, often called a zygospore, for some time. zygote[′zī‚gōt] (embryology) An organism produced by the union of two gametes. The fertilized ovum before cleavage. zygote
zygote [zi´gōt] the cell resulting from union of a male and a female gamete; the fertilized ovum (see also reproduction). More precisely, the cell after synapsis at the completion of fertilization until first cleavage. adj., adj zygot´ic. Development of the zygote. A, A sperm enters the ovum. B, The 23 chromosomes from the sperm mingle with the 23 chromosomes from the ovum, restoring the diploid number to 46. C, The fertilized ovum, now called a zygote, is ready for the first mitotic cell division. From McKinney et al., 2000.zy·gote (zī'gōt), 1. The diploid cell resulting from union of a sperm and a secondary oocyte. Compare: conceptus. 2. The early embryo that develops from a fertilized oocyte. [G. zygōtos, yoked] zygote (zī′gōt′)n.1. The cell formed by the union of two gametes, especially a fertilized ovum before cleavage.2. The organism that develops from a zygote.

Compare: conceptus2. The early embryo that develops from a fertilized oocyte. [G. zygōtos, yoked]zygote An egg (ovum) that has been fertilized but has not yet undergone the first cleavage division. A zygote contains a complete (DIPLOID) set of chromosomes, half from ovum and half from the fertilizing sperm, and thus all the genetic code for a new individual.zygote the DIPLOID (1) cell produced by the fusion of the nuclei of male and female gamete nuclei at FERTILIZATION.ZygoteThe result of the sperm successfully fertilizing the ovum. The zygote is a single cell that contains the genetic material of both the mother and the father.Mentioned in: Ectopic Pregnancy, Infertility, Infertility Therapies, Turner Syndromezy·gote (zī'gōt) 1.
