The diagram of eggs looks great - pictures paint a thousand words. But it contradicts both the text and the type II graphs.

So, which is it?

This is an important topic and deserves more than its present mention on Sex-determination system. However the present state of the article is so bad that I was tempted to let the prod tag stand: it reads like the summary of some academic paper rather than an article. -- RHaworth 20:34, 10 March 2007 (UTC)

GSD

GSD is linked here to "Glycogen storage disease type I", but it is not correct. GSD means (here) Genetic (or Genotype) Sex Determination.--Miguelferig (talk) 18:23, 1 May 2012 (UTC)

Australian Brush Turkey

The article states "... [TSD] is absent among birds, including the Australian Brush-turkey, which was formerly thought to exhibit this phenomenon." and then cites this source (external link), which seems to contradict the article, suggesting Brush Turkies DO exhibit TSD.

From the abstract: "In the Australian brush-turkey Alectura lathami, a mound-building megapode, more males hatch at low incubation temperatures and more females hatch at high temperatures, whereas the proportion is 1 : 1 at the average temperature found in natural mounds."

And from the introduction: "Here, we report that incubation temperature does affect sex ratios of hatchling Australian brush-turkeys, megapodes that build incubation mounds of organic material in which incubation heat is produced by microbial decomposition."

Unless there are any objections I'll make the edit.

The linked paper also states, in the abstract, "Megapodes possess heteromorphic sex chromosomes like other birds, which eliminates temperature-dependent sex determination, as described for reptiles, as the mechanism behind the skewed sex ratios at high and low temperatures" (emphasis added). They seem to be distinguishing between temperature having an influence on gender ratio at birth and gender being determined by temperature. I think this should probably be reverted. The article on Megapodes also contradicts this one, citing the same paper as evidence; either way one of them should be corrected. Rat (talk) 01:02, 5 May 2014 (UTC)

Planned Edits

I am planning on fixing some of the language and sentence structures throughout the article. I will also be verifying some of the provided information and sources as well as adding some updated information from 2019-2021. Biologiaphilosophus (talk) 16:26, 2 April 2021 (UTC)
