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.

zy·got′ic (-gŏt′ĭk) adj.
zy·got′i·cal·ly adv.

zy·gote

(zī'gōt)
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.

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.

zy·gote

(zī'gōt)
1. Diploid cell resulting from union of a sperm and a secondary oocyte.
2. Early embryo that develops from a fertilized oocyte.

1-4% of human zygotes were found to be 3PN, but there is less information about the chromosomal composition derived from these zygotes because 3PN embryos are generally discarded in routine IVF as they are thought to be genetically abnormal.
elegans zygotes. After using a technique called RNA interference to block the synthesis of specific proteins involved in the polarisation process, and observing the effects in live zygotes, they singled out a protein called Aurora-A (AIR-1 in C.
The zygotes were collected 5-20 min after spawning from the bottom of the beaker using a pipette.

To determine whether the SAC is engaged in response to oxidative stress damage in zygotes, we examined the localization of mitotic arrest deficient 2-like 1 (MAD2L1; also known as MAD2) and the protein kinase TTK by immunofluorescence staining.
Section 57(3) provides that '[n]o person may import or export human zygotes or embryos without the prior written approval of the Minister.
In all experiments, both pre-fertilization and zygote, our results showed that both crude extract and dolastane induced the appearance of anomalous zygotes, characterized by asymmetric plans of cleavage and atypical proliferations even at low concentrations (Fig.
As mentioned above, personhood proponents seek to attach legal personhood and, in particular, the associated right not to have life destroyed to single-celled zygotes. Presumably, this would mean that any form of contraception (emergency or otherwise) that can prevent pregnancy after the creation of a single-celled zygote would be potentially problematic.
The fertilized egg (zygote) has no more complexity than other body cells, which have identical DNA.
Again in chapter: 23; verse: 14, He explains the different developmental stages of the fetus in the mother's uterus and how He turns the Nutfah (zygote, which is the fertilized ova) into Alaqah (the divided cell that latches to the uterus); the Alaqah beomes a Mudhgha (embryo), which develops bones, which get covered with flesh.
The resultant zygote was activated and cultured in vitro and incubated under controlled environmental conditions over a week and later implanted into the uterus of an estrus synchronised recipient goat through laparoscopic technique.
