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.

/zy·gote/ (zi´gōt) the diploid cell resulting from union of a male and a female gamete. More precisely, the cell after synapsis at the completion of fertilization until first cleavage.zygot´ic

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.

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.
[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.

If a fertilized egg is a person, then women could potentially be held accountable for engaging in "risky" health behavior that could prevent implantation of that egg.
The egg cell's remaining material -- its cytoplasm -- would reorganize the genes of the patient's genome, so that the donor's genes would recapitulate each embryonic stem-cell stage their ancestral cells went through soon after the earlier formation of the fertilized egg that would become the recipient.
The fertilized egg contains all the DNA necessary for the embryo to develop.
They used fertilized eggs donated by couples undergoing fertility treatment, and which were unsuitable for in vitro fertilization (IVF), for the research.
So the term embryo was used to describe the fertilized egg.
Once a fertilized egg has gone through several rounds of division, stem cells form a bulge, called the inner cell mass, inside the early embryo.
One fact that the medical profession refuses to publish and which Alive also does not mention is that, in many cases, the pill acts as an abortifacient in preventing the fertilized egg from implanting in the walls of the uterus and thus causing the fetus to be aborted.

A fertilized egg normally splits in two within 24 hours, but no eggs had split after 36 hours, said researchers from the station, based in Ome on the outskirts of the capital.
Indeed, the typical result of 10 rounds of syringe injury was that the unfertilized egg released maximally measurable amounts of ATP into the external medium, whereas the fertilized egg released only a small fraction of this amount.
