If you record yourself saying Zygote, and play it backwards it sounds like Orgasm. Drrake (talk) 13:15, 16 November 2013 (UTC)[reply]
Actually, there is no 2n single-celled zygote in humans. When sperm enters egg, each replicates its DNA and then the pronuclei merge. That means you have a 4n single-celled zygote until the first cleavage into a 2n two-celled zygote (aka 2 blastomere stage).

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.
Learn to be your own teacher. Your own intuition and natural pattern recognition is greater than any book or any teacher. Books and teachers are for nothing more than to simply answer the questions that you do not have time to answer; time is gold when death lurks in the distance. In my opinion, if this stub is truly discovered to be faulty, it becomes a very good example of someone elses error (most likely by mistake) leading to the formation of a weak mind with a weak foundation. Weak minds are contagious by means of communication. Don't take my words or anyone's words to heart but see the essence of what is being said and use your "god" given intuition to act in the fashion which you beleive is correct. Newton, Mendel, Darwin, Einstein and others didn't simply accept what people told them, they basically went back to 1 + 0 = 1 and worked their way up from there. Once again this is just a simple man's opinion. LET UR KIDS SEE SEX

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?
Is the four celled zygote/embryo called forula, and the 8+ celled stage called a morula?
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.
We need a picture of an actual zygote, as per embryo, fetus, baby, child, adolescent, adult, etc. Junulo (talk) 17:05, 30 December 2007 (UTC)[reply]
how many chromosomes does a zygote have? —Preceding unsigned comment added by 75.17.113.74 (talk) 06:16, 15 January 2008 (UTC)[reply]
Not sure why this question ended up under the picture heading, but the number of chromosomes a zygote has will vary depending on the number of chromosomes of the adult organism. any zygote will have twice as many chromosomes as the sperm or ovum cell that produced it. In humans, a zygote has 23 pairs of chromosomes. More to the point, I don't think chromosome count belongs in the zygote article. Wilbiddle42 (talk) 07:02, 15 April 2009 (UTC)[reply]
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)[reply]
"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)[reply]
Are there occurrences that zygote plants elsewhere on the body of human (female or even stranger - male?) —Preceding unsigned comment added by 94.189.213.66 (talk) 21:22, 1 January 2011 (UTC)[reply]
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)[reply]

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.

It would be helpful if this article contained a pronunciation in the opening paragraph. 2A00:23C7:3119:AD01:754E:2E0:A2EC:AC8F (talk) 00:00, 26 October 2022 (UTC)[reply]

Everything not in the lead section was still in top-level sections.
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)[reply]
