[edit] Probably Wrong Information

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.

The article is correct, viz. biological life cycle. Better late than never, --Mgreenbe 14:51, 12 November 2005 (UTC)

[edit] How long?

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?

  • For humans, at "about" the fifth day it is considered an embryo. I'm not sure if this is the time of the very first division or not. Wikipedia also seems unclear, e.g. in Human development (biology). --JMD (talkcontribs) 01:23, 19 July 2006 (UTC)
  • 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 (talkcontribs) 14:52, 19 July 2006 (UTC)

[edit] Fourula, Morula...

Is the four celled zygote/embryo called forula, and the 8+ celled stage called a morula?

[edit] Biparental zygote

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.

[edit] picture

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)

how many chromosomes does a zygote have? —Preceding unsigned comment added by 75.17.113.74 (talk) 06:16, 15 January 2008 (UTC)
