Albino bristlenoses caused by exposure to light??

It is thought that the eggs of the bristle-nosed pleco are light sensitive; albino fish may be the result of exposure to excessive light.


I saw this statement in an ad on ebay, Is there any truth in it? I believed it was down to genetics.

This statment appears on Wikepedia HERE and is quoted word for word on severel websites. There is no evidence given to support this statement.

Like you I'm of the opinion that it's down to genetics, as for any albino animal or fish.

Doug, would know, but as both of you i am of that opinion myself.

Although it may appear on Wikepedia we all know that anyone can add things to this souce/font of knowledge whether it is true or not. In this case I believe that this is one of the latter.

I think this is probably a mis-quote from a different source that is more likely to have said something like "The eggs of an albino may be more light sensitive than the eggs of a common bn."

This is more likely to be true, as I believe that it is a known medical fact that all true Ablinos don't like bright lights as it hurts their eyes.

Albino"ism" is due to genetics and not the amount of light an egg has, if the other was the case then whole batches of eggs from common browns would end up being albinos when hatched in an egg tumbler rather than in a cave.



Jon

if it was down to light exposure then how come all the fish raised in egg tumblers are not albino?

Its based on genetics, give the wiki link and I will fix it.

I new you would shed some light on the subject....pardon the pun.

Wiki fixed!!!

don't know who the hack was who wrote it was but it is fixed now.

The albino morph is a not caused by exposure to light during development, it is a morph controlled by genetics

Hopefully that will put it to rest
