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.

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.
Collins Dictionary of Biology, 3rd ed. © W. G. Hale, V. A. Saunders, J. P. Margham 2005

Zygote

The 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.
