So, what, if any, IS the relationship between blondism and albinism then?[edit]

I have skimmed the article and the talk archive and have only found all sorts of irrelevant remarks about the subject of race, which (let's not forget that regardless of whether races exist or not, the phenotypical variations and the regional-ancestry-correlated morphological phenotypes – or groups of similar phenotypes – that form the basis of any racial classification do damn well exist) is completely unrelated to the undubitably real phenomenon of blondism – or light-hair-eyes-and-skin-in-Europeans-(that's-not-albinism)-ism, for want of a better term –, but no insight on the issue that I'm sure a lot of readers are wondering about: if H. sapiens sapiens was originally coloured some shade of brown, clearly many people in the north of Europe (to varying degrees) have a condition similar to albinism even if not quite as extreme (low-melanin-ism?), a condition that happens to be inherited recessively as well, so what exactly has happened and how is it related to albinism? Don't dance around the issue, swallow your political-correctness-caused inhibitions and get us the straight dope! Finally! What gives?!

For what it's worth, the German article states:

Albinism is mostly inherited recessively and in humans worldwide occurs with a frequency (prevalence) of 1:20.000. Clusters are found above all in Africa with a prevalence of 1:10.000 and higher. The light skin colour of the Asians and Europeans is to explain by albinism of type OCA 4, the blond hair and blue eyes of the Europeans by OCA 2 and a further gene.

So, from this, we learn that first yes, albinism is really more frequent in Africa, it's not simply an illusion caused by the higher visibility of albinism in dark-skinned "negroid" phenotypes, and second, light-skin-ism and light-hair-and-eyes-ism respectively are caused by some type of albinism genes, see OCA2 and the table in the German article. I see no reason to censor or omit such information for reasons associated with misunderstood political correctness. --Florian Blaschke (talk) 03:27, 25 July 2014 (UTC)

The relationship is that albinism is usually a single-gene genetic trait causing variable phenotype hypopigmentation and low vision. Blondism is a multi-gene adaptation to low sunlight and low-fish diet lowering skin pigmentation and increasing vitamin D intake, possibly enhanced with sexual selection lowering both hair and eye iris pigmentation without damaging loss of RPE pigmentation levels. In Tanzania, the common OCA2 deletion mutation may be a heterozygous-advantage adaptation, but nobody knows what its actual purpose is. --84.250.122.35 (talk) 22:54, 25 December 2016 (UTC)

Some of this isn't right; people are confusing genes with names like OCA2 and the medico-genetic conditions with the same and similar abbreviated names. Some of the genes that cause some forms of albinism are also "used" without ill effect in the phenotypic expression of the skin tones of Europeans and various Asian groups; others produce red hair, or light eyes, etc.. But this doesn't make these "racial" traits a form of albinism. The genes are named after the condition, not the other way around. By way of analogy, the entire zoological family Canidae is named after the genus Canis (Latin for dog), but not everything arising from that family is a dog; it includes foxes and jackals.  — SMcCandlish ¢ ≽ʌⱷ҅ʌ≼  02:07, 22 September 2017 (UTC)

Some suggestions for this page[edit]

1) Expand on the rare OCA forms inherited from one parent (genetics section). What are these rare forms? Does single-parent inheritance mean the parents are homozygous for the trait as well? How do these forms compare to the other OCA forms? 2) Statistics on albinism prevalence throughout the world would be a great addition to this page! 3) The hyperlink for OCA2 (genetics section) leads to a page with quite a bit of information on the OCA2 gene. The same cannot be said for the OCA1 link. Does anyone have any information on OCA1? This would benefit the main albinism page.

Regarding this - we use papers published in peer reviewed journals. --NeilN talk to me 13:30, 17 October 2014 (UTC)

Albinism as biology?[edit]

As usual in these cases, we have an article which is 90% medical, and which does not even mention albinism in other organisms until one reaches the very bottom of the article. Albinism is a biological phenomenon, and human albinism is just one aspect of this phenomenon. Medicine is just one aspect of human biology. Biology should not be treated as a subset of medicine. Invertzoo (talk) 22:18, 8 January 2015 (UTC)

I made the same argument the last time the title of this article came up (it was original Albinism in humans, and the article presently at Albinism in biology was at Albinism; the human article is a later split-off of that more general article. Anyone can propose another requested move if they think they can make a good case for reversing this situation. That said, there is no big emergency; the very top of this page has a hatnote that links prominently to Albinism in biology, and there's no evidence people are getting lost or confused.  — SMcCandlish ¢ ≽ʌⱷ҅ʌ≼  02:12, 22 September 2017 (UTC)

I don't understand[edit]

"The prevalence of albinism in some ethnic groups in sub-Saharan Africa is around 1 in 5,000, while in Europe and the US it is 1 in 20,000.[15] It would follow, then, that there would be stronger selective forces acting on albino populations in Africa than on albino populations in Europe and the US. Rates as high as 1 in 1,000 have been reported for some populations in Zimbabwe and other parts of Southern Africa."

That seems like it should be the other way around. If it's more common in Africa wouldn't that imply there were weaker selective forces there (assuming that the text is referring to negative selection and not positive selection). FiredanceThroughTheNight (talk) 00:04, 2 August 2015 (UTC)

"assuming that the text is referring to negative selection and not positive selection" There you go. Maybe OCA2 heterozygous persons have some advantage in Africa, but not in Europe or US. It could also be, that the whole follow is OR. --84.250.122.35 (talk) 20:29, 16 February 2016 (UTC)

Semi-protected edit request on 4 August 2015[edit]

I wish to submit a new link on the external link 4 it does not work Tomphiri (talk) 10:15, 4 August 2015 (UTC)

You need to be more specific, what's the link? Doug Weller (talk) 10:17, 4 August 2015 (UTC)
Don't bother. I assume it's your blog, and we rarely accept blogs, see WP:EL. The blog also contains copyright material from another source, and we don't link to sites with copyright violations. As for the original source, I don't see how the article adds to our article, and it's not by a recognised expert. Sorry about all this but I'll add some links to your talk page to help you edit.

Picture Caption Inaccuracy[edit]

Resolved: The pseudo-ethnicity has been removed.

The caption for this page reads, "An albino boy of black ethnicity". Please note that 'black' is not an ethnicity, it is a racial category. I would suggest a more accurate description, such as, "An albino boy of X ancestry". For instance, if he is American, the caption could read, "An albino boy of African-American ethnicity," or if he is from a country in Africa it could read, "An albino boy of Hausa/Zulu/Etc ethnicity". Please identify this boy's ethnicity and attend to this immediately, or find an alternatively acceptable and more accurate method for labeling this caption. — Preceding unsigned comment added by 137.158.134.120 (talk) 14:32, 2 October 2015 (UTC)

Persecution of people with albinism[edit]

I know we have a separate article about Persecution of people with albinism, so I will put the same on the talk page there as well. But it's likely that more people are watching this page here. Therefore, does anyone know about whether people with albinism have it "tougher" in African societies than in European ones? One would think so for various reasons, one being that it is not so ovbivous in a society with mostly white skinned people. Second one being that the sunburn issue is not such a big one. But do we have anything beyond a gut feeling about this? If yes, would be good to add it in the society and culture section. EMsmile (talk) 21:38, 3 August 2017 (UTC)

Well, just read that article. I think being hunted and murdered in large numbers by gangs of crazy witchdoctors qualifies as "having it tougher".  — SMcCandlish ¢ ≽ʌⱷ҅ʌ≼  01:52, 22 September 2017 (UTC)
