Talk:Maternal effect

message: I think that maternal effect and maternal inheritance are distinct phenomena. I've never seen the term "maternal effect" used to describe maternal inheritance of DNA. The two phenomenon are clearly distinct (both in classical genetics and molecular genetics). AdamRetchless 02:55, 23 Mar 2004 (UTC)
replies: text: You're right.  They are distinct phenomena, and the distinction is very important in elucidating how each event happens.  I'm changing the article and some of the articles it references to reflect this. GuildNavigator84 12:26, 4 May 2006 (UTC)

text: I also agree.  I have never seen "maternal effect" used to describe maternal inheritance.  I have consulted three authoritative references, and all three distinguish clearly between the two terms.  I am going to change the second paragraph to remove this confusing statement.

text: Interesting. Kirkpatrick and Lande (1989; The Evolution of Maternal Characters. Evolution 43:485-503) separate maternal effects into 2 distinct classes, 1 of which they term "maternal inheritance", the other "maternal selection". I would regard Kirkpatrick and Lande as authoritative authors in this field. Perhaps they use maternal inheritance in a different sense to the references you consulted?

thread_title: Maternal effect or Maternal inheritance?

message: This article implies that only the maternal genotype can influence the phenotype of offspring. However, there are copious examples in the literature demonstrating that aspects of the maternal phenotype can influence offspring phenotypes, some have even shown that this can be independent of maternal genotype (e.g. Marshall & Keough 2004, Marine Ecology Progress Series 272. pages 301-305). Offspring size, for example, is one of the most intensively studied maternal effects and has been shown to vary with maternal age, maternal size, maternal growth rate, maternal nutritional condition, maternal hormone concentrations, etc. I would suggest that the article is modified to reflect this. If nobody has any objections I would like to make this change. I'll wait a few weeks to allow for any feedback.

thread_title:  maternal phenotype can influence offspring phenotype 

message: Images from Drosophila embryogenesis could be useful. Tim Vickers (talk) 16:42, 7 May 2008 (UTC)
thread_title: Images

message: Much of the content of this article seems to be rather a sketchy and not greatly accurate description of axis specification in the Drosophila embryo, with barely any attempt to describe why these mutation in these genes have maternal effects. (Apologies if this comment comes across as the sort of thing I would write when marking an essay - it is meant to be constructive). I therefore propose to delete or move much of the content, so we can get back to explaining maternal effects. Any comments? Celefin (talk) 23:23, 11 April 2009 (UTC)
replies: text: This squares with the remarks about the maternal phenotype above. --Crusio (talk) 08:38, 12 April 2009 (UTC)
replies: text: Ok, I am finally starting to reconstruct this article. Please everyone feel free to chip in and correct what I am writing. Celefin (talk) 14:00, 20 June 2009 (UTC)
replies: text: Can anyone suggest or contribute an illustrated example of non-genetic maternal effects with images that are suitably licensed for use in wikipedia? Celefin (talk) 19:28, 4 July 2009 (UTC)
thread_title: This article is meant to be about maternal effects

message: I note that there are relatively few references in this whole page, including whole paragraphs.  I also generally feel that the article is not altogether encyclopedic in style.  For example, I am not sure that we should describe this effect as "legitimate", since in scientific theory its all about "currently generally accepted or something, isn't it?

replies: text:  I tagged the least-cited sections some months ago. The tone isn't too far off. The effect is certainly a legitimate hypothesis and probably somewhat more than that. We certainly shouldn't imply it is all accepted, but it is a serious scientific idea and evidence has been sought and presented. Chiswick Chap (talk) 12:18, 30 December 2017 (UTC)
thread_title:  Article Quality? 

message: There is a long-standing article at Telegony (pregnancy) which seems to cover some of the history of the maternal effect, and something needs to be done to relate the two articles. This could be a full merge, or the addition of a cited summary section with main link to Maternal effect and something similar at the other end. What do other editors think would be best?
