[edit]

The textbook I referenced has some of the information that I added but not all. The information is, for the most part, verifiable through Google searches, looking at the context in primary literature and in the lecture slides posted online by various teachers. If anyone has any better textbook or review article references to cite, please do so. IlliniWikipedian 18:01, 1 December 2005 (UTC)[reply]

Under Mechanisms, the link to "Asters" leads to a flower... This must be a mistake , 88.154.152.18 13:09, 12 March 2007 (UTC) Anat[reply]

Why is there a page for "spiral and radial cleavage" but no page for holoblastic cleavage. It seems like a very strange idea for a article; grouping two (of the four listed here) types of holoblastic cleavage together. I think there needs to be a separate page for holoblastic cleavage or just merge the spiral and radial cleavage page into Cleavage (embryo). Jack (talk) 19:51, 16 January 2008 (UTC)[reply]

Yes, I tend to agree. This isn't a particularly long page and the articles aren't going anywhere fast. I merged spiral and radial together as well as determinate and indeterminate, but that was just a start. Merging both of them here sounds like a good idea to me. Just remember to add a merge template to this page too (multimerge is the one you'll want). Richard001 (talk) 06:15, 18 January 2008 (UTC)[reply]
Okay I've redirected this page as all the information (minus the links) was exactly the same. Jack (talk) 18:07, 24 February 2008 (UTC)[reply]

Some of the same reasons as above. They should be merged with cleavage as there is little content. Jack (talk) 22:53, 17 January 2008 (UTC)[reply]

Fine with me. Richard001 (talk) 05:28, 3 March 2008 (UTC)[reply]
Okay that's done, though I think I've put it in the wrong place. Anyone with a little more knowledge want to sort it out? Cheers, Jack (talk) 04:39, 20 March 2008 (UTC)[reply]

Summary

[edit]

In the summary, I'm not certain if the marsupials have radial, rotational or other type of cleavage (nothing was said about it in the books of Gilbert and Kardong). Comparing this illustration [1] (figure 11.21) and this other [2] (p. 46), I think they have rotational cleavage.Zorahia (talk) 23:04, 21 August 2013 (UTC)[reply]

Proposed merge of Morula into Cleavage (embryo)

[edit]

One or two lines would describe the morula. Page includes details of compaction and blastocyst. Better presented on Cleavage#Compaction Iztwoz (talk) 16:55, 19 October 2022 (UTC)[reply]

I agree. Most of the content currently on the page on morula would better belong to the page on cleavage. User8647 (talk) 09:28, 21 December 2022 (UTC)[reply]

Cleavage in monotremes

[edit]

Among monotremes such as platypus and achidines, cleavage during early stages of embryonic development is somewhat unusual from other Monotremes have a form of cleavage known as meroblastic cleavage.This suggests that only a portion of the york cleaves due to large yolk.

Here is a little explanation how it works:A significant number of monotremes have a large concentrated yolk to sustain embryonic development.

Cleavage pattern: Partial cleavage in monotremes occurs in the blastodisc, a little area that sits on the top of the egg yolk.This causes the disc to form a flat instead of a solid ball.

Development: Following the initial cleavage,the cells begin to specialize to produce various tissues.Monotromes continue to grow outside the mothers body after laying their eggs.

This cleavage pattern of monotremes highlights their evolutionary adaptations and sets them apart. Tony Nyandieka (talk) 08:04, 31 October 2024 (UTC)[reply]

That is totally unsourced and this is not the place to paste your homework - the article has had to be protected to prevent such random additions - please explain this to your teacher. - Arjayay (talk) 11:22, 31 October 2024 (UTC)[reply]
