Talk:Haplodiploidy

Trimming
Thanks to everyone who contributed the info about honeybees but remember, this article is about Haplodiploid sex-determination. The stuff about honeybees belongs in the honeybees article. Also, please include references if contributing in the future. Please don't be discouraged though, this article needs help and well-referenced, salient info would be very much appreciated.

Haplodiploid sex-determination system → Haplodiploidy

I strongly recommend you move the page to the simpler title of Haplodiploidy. I have rewritten the intro on the basis of the two sources added, which are of the highest standing in their fields. Macdonald-ross (talk) 09:52, 15 June 2012 (UTC)

Relation to X0 sex-determination system
There should be a statement in this article giving the relationship of this system to the X0 sex-determination system. As I am not knowledgeable, I could not figure out whether it is considered one form of X0 or a similar but distinct system. If I have it right, it seems that an X0 organism normally is diploid in all the autosomes, but the male has only one X, whereas only the latter is true in haplodiploid, the former is not for the male. Whatever the case, the article should answer this, it seems to me. -R. S. Shaw (talk) 19:09, 15 June 2012 (UTC)


 * The basic X0 determination system operates like an XY system with no Y genes. It does not have the major genetic and evolutionary consequences of haplodiploidy. Haplodiploidy is often cast as a type of parthenogenesis, because the eggs which produce the males are not fertilized. Macdonald-ross (talk) 17:23, 16 June 2012 (UTC)

Arrhenotoky
I'm afraid we have something else to think about. This wiki also has a page on Arrhenotoky or Arrhenotokous parthenogenesis. These terms mean exactly the same thing as Haplodiploidy, and a merge is in order. The merge should be made into this article, which is much more substantial than the other. Macdonald-ross (talk) 08:25, 16 June 2012 (UTC)
 * expanded the article on arrhenotoky to cover the different meanings that are non synonymous to haplodiploidy.Staticd (talk) 21:36, 18 June 2012 (UTC)
 * First prove your claim that arrhenotoky covers more meanings: see my note on Arrhenotoky (talk). Macdonald-ross (talk) 13:04, 19 June 2012 (UTC)

Controversy
The 'Controversy' section (not written by me) contains a statement that "eusocial drones help raise their brothers in addition to their sisters". In the context of eusocial evolution, this is a big claim, and if true not known to me. Surely, worker bees (female) do the work, and drones... do not? Anyway, it really does need a citation.

Clarification on a sentence
One of the paragraphs states that there haplodiploid system determines sexes in all members of the hymenoptera group, but I recall that the Cape bee operates under thelytoky. When the word 'all' is used, does that simply mean that it is reported in all members of the hymenopteran group, or every single species?

Fertile diploid males
The statement that diploid males by necessity sterile or inviable is not true. Albeit for the most studied species this statement is true, there are now at least two examples of species in the Hymenoptera order in which diploid males can reproduce.

Cotesia glomerata https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2696080/

Euodynerus foraminatus http://www.pnas.org/content/101/28/10374.full

I would also advise to mention the term single locus complementary sex determination (sl-CSD), which is a term used for this type of sex determination (I know people like to invent new terms, and I'm fine with the old haplodiploidy, but others might look for this term after they encounter it).

Work needed
Since it seems there are students working on this article, here are some tasks that need doing.

1) Format all refs (old and new) using the template.

2) Edit the lead (introductory) section, moving all refs out into the body of the article (if they aren't there already, or if they're defined in lead and used in body).

3) Rewrite lead to summarize the body of the article.

It may be as well to remind everyone that all new claims of fact need to be cited. Chiswick Chap (talk) 09:26, 3 November 2015 (UTC)
