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.

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.

zygote

[zī′gōt]
Etymology: Gk, zygon, yoke
the combined cell produced by the union of a sperm pronucleus and an egg pronucleus at the completion of fertilization until the first cleavage. Also called zygocyte.

1. The diploid cell resulting from union of a sperm and an oocyte.
Compare: conceptus
2. 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.

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.

zygote

the cell resulting from union of a male and female gamete; the fertilized ovum. More precisely, the cell after synapsis at the completion of fertilization until first cleavage.

Bower had "thought that the fruit-body of Coleochaete supplied a prototype of an undifferentiated mass of cells, all fertile, such as this theory contemplates," but he was forced to retreat from this position because "it has now been shown that in Coleochaete reduction occurs at the first segmentation of the zygote, and accordingly the old comparison is no longer permissible" (Bower, 1908; p.

37) Perhaps it is the sexual conjugation of these two gametes, with the resultant admixture of DNA and the crucial event of genetic recombination, with its unpredictability in terms of the resultant new phenotype, that imparts the specific moral boundary--a kind of cosmic biological "singularity"--that is afforded to the zygote and its subsequent developmental forms.

Finding this a little hard to believe, I tried a few more obscure words out - and it seems that it could be true, certainly if you wanted to register zygote, yaws or wimple.
Biebi (1962) suggested that an increased zygote yield correlated with a slight rise in pH value of the medium, but the effect was rarely as much as twofold.
