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

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)[reply

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)[reply]

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 ☺ ☏ ¢ ≽ʌⱷ҅ᴥⱷʌ≼  02:07, 22 September 2017 (UTC)[reply]

Some suggestions for this page

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.

Albinism as biology?

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.

I don't understand

"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)[reply]

"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)[reply]

You need to be more specific, what's the link? Doug Weller (talk) 10:17, 4 August 2015 (UTC)[reply]
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

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)[reply]

Persecution of people with albinism

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)[reply]

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 ☺ ☏ ¢ ≽ʌⱷ҅ᴥⱷʌ≼  01:52, 22 September 2017 (UTC)[reply]

Sunscreen info

I found a later version of "Facts About Albinism" (King, et al., 2004) [1] with information on sunscreens and albinism that was missing in the previously cited version. It's already added in the article, for what it was originally cited for. It hasn't been used for sunscreen info or anything else yet.  — SMcCandlish ☏ ¢ >ʌⱷ҅ᴥⱷʌ<  17:31, 10 November 2017 (UTC)[reply]

Pictures need diversity

The extant photos are only showing people of African and New Guinean descent. Albinism often looks different (more yellowish) on people from dark-complected ethnicities, so a European and/or Asian should probably be re-added to the article.  — SMcCandlish ☏ ¢ 😼  09:48, 22 June 2018 (UTC)[reply]

Discussion

It seems to me that when people refer to

albino
, to refer to albanism in that context would be seen as rather stuffy and pedantic, while to refer to a person as an albino could be at least mildly offensive, instead we say they suffer from albanism.

I see there are two spellings of the term, albinism and Albanism. The first is far more prevalent, and is what is used in ICD10 so I would propose albinism is kept even if other changes are made. jamacfarlane (talk) 10:55, 10 July 2018 (UTC)[reply]

We have two articles:

  • albanism
Correction, this is currently at Albinism (note spelling difference I've highlighted above) jamacfarlane (talk) 10:55, 10 July 2018 (UTC)[reply]
    • albino
      also redirects there (which seems just plain wrong to me)
  • albinism (biology)

As I said previously, I think we should disambiguate both articles. This will get most readers to the article they want by the shortest path. Andrewa (talk) 03:06, 10 July 2018 (UTC)[reply]

Aside from "albanism" not being a word in English (that's a typo redirect), this idea of a meaning/referent bifurcation is pure
original research/supposition
, not supported by actual facts. "Albino" is simply the older, less technical adjective (albinistic being the newer, more technical one).
  • Albinism: [3]. It's used generically about humans, lab rats, etc. There is no basis for the idea that it's a special human-referent word.
  • Albino: [4]. Very frequently used in reference to people in the mainstream press. However, the usage is slowly starting to take on the character of a politically incorrect epithet when used this way; the polite term is person/people with albinism or albinistic person/people.
That last bit, however, is a reason that
Albinos shouldn't redirect to an article focused on humans, that the main article on the topic should be the generic one.  — SMcCandlish ☏ ¢ 😼  03:44, 10 July 2018 (UTC)[reply

Quite correct, I did mean albinism, consistently!
There is no basis for the idea that it's a special human-referent word. Agree. That is not what I said at all.
Very frequently used in reference to people in the mainstream press. Interesting... Your first few hits are all from Africa, the next one is objecting to the use of the term. Then comes a chipmunk. I think this supports the idea that this term shouldn't be restricted to other animals, or to human beings... which is what I was saying. Disambiguate both.
Certainly agree that the main article on the topic should be the generic one. But that's not the same thing as saying it should be at the
base name. And your evidence suggests otherwise. Andrewa (talk) 04:20, 10 July 2018 (UTC)[reply
]
Um, no it doesn't. And see
WP:PRIMARYTOPIC. We do not disambiguate without a reason to do so.  — SMcCandlish ☏ ¢ 😼  04:29, 10 July 2018 (UTC)[reply
]
It doesn't? Your evidence suggests that both words (albino and albinism) are commonly used in both senses. This is not proof that we should disambiguate, but to say that it doesn't suggest it seems rather strange. It's evidence, and should be part of the decision, not just dismissed.
We do not disambiguate without a reason to do so. Agree.
And BTW, it seems that we might both have been wrong in thinking "albanism" not being a word in English. It happens. But I did mean to type albinism, you got that much right.
The bottom line is just what will best assist readers. With various strong opinions among editors as to what these terms most commonly and naturally mean, it's not a trivial question (and that is a reason to disambiguate). Andrewa (talk) 23:28, 10 July 2018 (UTC)[reply]
It doesn't suggest what you think it does, because these are not separate topics with a coincidentally overlapping name like
natural disambiguation when feasible). PS: Someone thinking "albanism" is a legit spelling doesn't make it so; the source cited does not include that spelling, nor do any major dictionaries I've checked. It's just a common typo. I did encounter it as a typo in the headings of two ostensibly reliable sources, but they used "albinism" in their main texts, and it seems to have been an error of whoever webbified the articles.  — SMcCandlish ☏ ¢ 😼  21:05, 11 July 2018 (UTC)[reply
