? about Albino Axies genetics

alright, I've been looking at some of the axolotol genetic information lately, and I dont quite understand it fully, and my question has to do with why albino axies dont ever retain pattern? Is there a record of an albino axie thar has retained pattern? Picture?

If any one can explain in the most simple form why axies do not retain their patterning like most albino animals, I'd greatly appreciate it. This genetic information is so strange to me from species to species.
 
Albino axies do. Which is why they are gold (w/ red eyes). There is also a white colour morph which is not an albino (black eyes). Combine these two and you get a plain white with red eyes.
 
Golden albinos often show a wildtype 'pattern' (mottled dots and such) because of the xanathic (yellow) cells still being present. white albinos (and melanoid albinos, I think), lack these xanathic cells and don't show any patterns. Unless white on white is a pattern.
 
Joan is sort of white... I beleve from things ive read and have been told that white albino axies are melanoids as they do not have any colour present...

If a White with black eyes breeds with a gold with red eyes, it doesnt mean it WILL have white with red offspring.. Depending on the genes that it got from its parents will depend on what offspring each animal will have.

I have Mikki's genetics table on my work pc and i will post it up tomorrow... It shows the theory behind the colours..

I'll post it as soon as i get a chance tomorrow..

Just a side note if anyone is looking for Mikki.. he will hopefully be back on the forum sometime around Friday.. This is due to a VERY heavy work load.. If you do have any problems, either email him or me and i'll try and chat to hi at some point.. Otherwise contact one of the other mods.
 
thanks for the replys! That makes a lot of sense. I always thought thats what a golden albino was, but I've heard theories of albino tiger salamander genes being mixed in, so I wasnt sure how that played out genetic wise. And I havent really seen too many golden albinos to get a chance to notice too much of the mottled pattern on them I suppose.
 
Coincidentally, I'd emailed the Indiana University Axolotl Colony last week asking them about the tiger genes. They've sent me some PDF files, but something went wrong with the attachment and I can't open them

I've asked them to try resending, and will let you know what the articles say once I've read them. IUAC is also mailing another article to me that wasn't available in electronic format. If it's interesting, I'll pull up this topic and post an update later (has to be mailed from the US to Australia.)
 
Kim, the melanoid phenotype m/m is not related to the albino phenotype a/a, so not all albinos are melanoid, and not all melanoids are albinos. All the color genes are inherited seperately, and that's why we get so many variations.
 
Doh, i should have known that!.. I've just hatched and rasied a black melanoid!

I'll put me head back on now :D
 
gah, Microsoft is trying to own me lol. They want me to buy excel to open up your file there. Go figure. I'll wait to see if we get that pdf file about the mixed in tiger genes or not before I go off and pay for excel lol.
 
Kyle, if you're still interested it would be worth emailing the Indiana University Axolotl Colony and asking them if they could send you a copy of the article I received today: "Albino axolotls from an albino tiger salamander through hybridization" They went far beyond what I'd asked for and even sent me back issues of a bunch of their axolotl newsletters- now I have a ton of reading/learning to do!

This new article is WAY better than that pdf I sent you. This one is an illustrated copy of the lab write-up that describes the procedure in great depth and even has photos of the original animals involved. There's a lot that I don't really understand, but I still found it really interesting!
 
Thanks for the heads up on that Leah. I'll shoot an email off to them. Although colors and genetics are not my main interest in Biology, I will be a biology major none the less starting next fall. I'll have to learn a lot of these types of things any way. So yeah, I'm still extremely interested in what this whole thing entails, and I'm curious to see what else I can learn about it.

I smell the beginnings of a great research paper for one of my classes
