message: I'm no developmental biologist but I believe that meiosis occurs before fertilization of the oocyte (for egg and sperm formation). Any expert please correct this and expand if possible. America has already polluted my mind and I only hope to rid its citizens of further contamination. 
:meiosis is already complete in the sperm. the egg is frozen in metaphase of meiosis II. fertilization triggers its completion of meiosis. then the sperm's 1n DNA pronucleus approaches the egg's 1n DNA pronucleus. meanwhile DNA is replicated, so we have 2n sperm DNA and 2n egg DNA. the pronuclei merge and immediately begin mitosis, which after cytokinesis results in two 2n blastomeres.

message: How long is a zygote a zygote? Or how long is it from the time that it forms to the time that it begins splitting?
: 30 hours. then it completes the first mitosis into 2 blastomeres. Kleinburgerei (talk) 11:44, 21 February 2015 (UTC)
replies: text: * According to "Psychology" (Lefton, 2006), implantation in the uterine wall is what causes it to be an embryo. (First division occurs within ten hours). Makes sense. If someone can confirm this distinction from a more general medically source, the article would benefit. --JMD (talk • contribs) 14:52, 19 July 2006 (UTC)
replies: text: Implantation is when the embryonic stage begins. After cleavage begins, the proper terminology is, I believe, morula, then blastocyst. 75.118.170.35 (talk) 16:34, 7 December 2009 (UTC)
thread_title: How long?

message: Is the four celled zygote/embryo called forula, and the 8+ celled stage called a morula?
:lol, is that a pun? the etymology of morula is the Greek word for "mulberry", not "more" as in more cells. it consists of 16 cells. Kleinburgerei (talk) 11:45, 21 February 2015 (UTC)

message: in reference to merging the two article, i would think it best to merge them. given that the article on Biparental zygote is nothing more then a definition, i think it would fit best under a subheading of zygote.

replies: text: Agreed about how this article ended up in this section. A zygote is a diploid organism, meaning that it receives genes from both parents. It has both sets of chromosomes, as Wilbiddle42 states.--MrNiceGuy1113 (talk) 19:47, 26 April 2012 (UTC)

message: Ok, I'll do it.  For some reason, User:Spotfixer finds this language inappropriate, poor written and/or biased.  I disagree and instead of WP:ANI, this belongs here.  I've reinserted it.  -- Ricky81682 (talk) 22:09, 15 February 2009 (UTC)
replies: text: Ok, a possible odd concern is that the language implies zygote => blastocyst while the infobox goes to embryo and the template goes to Cleavage (embryo).  If someone could clarify that.  -- Ricky81682 (talk) 22:13, 15 February 2009 (UTC)
replies: text: Embryo = from zygote to nine weeks, at which time it's a fetus. arimareiji (talk) 22:20, 15 February 2009 (UTC)

text: I.e. a zygote, a blastocyst, an embryoblast, etc are all embryos. arimareiji (talk) 22:23, 15 February 2009 (UTC)
replies: text: Is the time period given by Arimareiji (zygote to 9 weeks) for a human, mammalian organism, etc.?--MrNiceGuy1113 (talk) 19:51, 26 April 2012 (UTC)

text:  No, I generally understand.  I suspected it was just a matter of using terms generally and specifically at the same time.  Just pointing out something someone should clarify.  Frankly, I'm just surprised this article is just a stub and isn't a hostile controversial mess (for what that's worth).  Also note that blastocyst claims five days, not four.  -- Ricky81682 (talk) 22:25, 15 February 2009 (UTC)

thread_title:  Lead language 

message: "Fertilized egg" redirects here, however there are no fertilized eggs; when the egg and sperm join, they form a zygote. A zygote is not an egg. 75.118.170.35 (talk) 16:36, 7 December 2009 (UTC)
replies: text: I think that this question can be up for debate. I have seen a fertilized egg defined as the moment an egg and sperm join or when the egg starts to undergo development. Someone who has a degree in developmental biology really needs to say if fertilized egg is an appropriate redirect to this page.--MrNiceGuy1113 (talk) 20:01, 26 April 2012 (UTC)

text: However, I just read that when an egg is fertilized it is not longer considered and egg and is now a zygote.--MrNiceGuy1113 (talk) 20:09, 26 April 2012 (UTC)

text: I think that "fertilized egg" is common usage for zygote even though it is technically incorrect. Thus the redirect seems appropriate to me. --Biolprof (talk) 18:02, 29 June 2012 (UTC)

thread_title:  Zygote planted elsewhere on the body 

message: Since a zygote is a single cell after fertilization, I do not think it exist for 5 days and then immediately becomes a multi-cellular blastocyst on the fifth day. It cleaves to form blastomeres.Clucaj (talk) 14:26, 26 March 2013 (UTC)

message: This section should be removed. It describes asexual reproduction of a single-celled organism and not sexual reproduction: only in the latter you have gametes and a zygote. In some Protozoa one can observe sexual reproduction, but it's very different from the process described in this section and is very variable depending on the species.

message: Everything not in the lead section was still in top-level sections.
* So I grouped the sections about multicellular life under one section, using some info from the lead section and the entire section on "Reprogramming to totipotency" as the section content not in subsections. The section on unicellular life was basically just renamed from "In other species," but had some corresponding info from the lead section.
* The section on Fungi was almost all about karyogamy, which that page indicates is what happens in all sexually reproducing eukaryotic life, so I moved most of that to the lead section.
There was one line at the end of the lead section about the biologists who had made some of the earliest discoveries about zygotes, so I separated that into a new History section, hoping to encourage future editors to add to it.
While I was at it, I requested citations for anything not already cited that seemed significant but not obvious. Feel free to ask me any questions or to modify my work, but please don't revert without a good reason. This was a good faith effort. ~ MD Otley (talk) 21:30, 23 March 2024 (UTC)
