Genetics - my babies are multi coloured!

[yellowpebble]

Ok, another genetics question. I'm not totally lost when it comes to genetics, but i'm no genius either.

The babies from a copper x black melanoid mix have been interesting. I kept all 208 of them.

- I have about 50% wild type of light and dark shades, some probably melanoid.

- about 40% golden albino, they are very yellow, but again varying shades.

- 5% are ghost white, you can barley see them, they are almost grey. White albino? Maybe a very light golden?

- 5% leucistic, dark eyes, they look like a very very pale wild type, but are loosing the brown slowly.

I will take pictures of each tonight.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The copper male is very deep brown/yellow/orange and has what looks like dark eyes. But on closer inspection the middle is totally red. He has a dark black/silver shiny ring and a red middle. He must be a/a albino for any albino offsping. And the melanoid must be carrying albinism.

but how do the leucistics and white albinos come out... is it even possible to have 4 different colours in one batch? I didn't think enough genes existed in both parents to match up to all of these colours.

Can anyone work out the genes of the parent’s from this? It would be very much appreciated. I am lost.

Wildtypes are A/a or A/A, D/d or D/D, M/m or M/M, while melanoids are m/m.

The ghost-white/grey ones may be melanoid albinos: a/a, m/m (the D gene may or may not be expressed here).

Golden albinos are a/a, D/d (or D/D).

Since the genetics of "Coppers" aren't completely understood, you're guess is as good as mine. He doesn't have to BE albino to have albino babies. He just has to be a carrier. But he's probably:
a/a (albino, especially since a large % of the babies are albino), D/d, M/m

Your melanoid is:
A/a (albino carrier), D/d (not leucistic), m/m (melanoid)

Leucistics come from having two carriers of the d gene. White albinos are just albinos that have two copies of the d gene. So Leucistics are A/a (or A/A), d/d, and white albinos are a/a, d/d.

Given the right genotypes, the offspring can be a rainbow of colors. It just depends on what the parents are carrying.

Kaysie, where were you when I was doing my genetics module in my first year of uni! :lol: I sucked really bad at genetics, I really have trouble grasping it. The whole Hardy Weinburg Principle was so confusing to me.

Kaysie, that was very well worked though! I've red it over about 10 times and i'm getting the drift finally. I tried to rep you but i don’t think it can go any higher...

I got the punnet squares out and your info matches up. sweet.

What does an adult melanoid albino look like? :/

 

[Kaysie]

Lol, in high school, I did an independent study in genetics. I really wanted to go into human genetics and diseases related to heritable autosomal traits and essential amino acid synthesis.

In retrospect, I would've made WAY more money!

 

[scooty16]

Nooooo! Not the punnet squares! Anything but the punnet squares!

 

[Kaysie]

I love punnett squares.

An adult melanoid albino is creamy white to faintly pale yellow, with no shiny-gold bits.

Wow! you are so lucky to have such a diverse batch of babies! You should upload pictures of them as they grow so we can all see what they look like now and what they develop into!....also pics of mommy and daddy...I would sure love to see them
Are you selling them or giving them away?

I got 22 of her last batch last week and they are currently hatching I think so far I have 1 golden, 2 white albinos, 2 leucistic and 7 wild types. Only a guess though as they're SO small!

I got excited there for a minute. I saw "multicolored" and thought that the infamous "harlequin" type had resurfaced. <puts checkbook away>


The fun part with axolotl larvae is when some of them decide to change coloration as they grow.

Speaking of colours, got photos?
And on another note, is there a thread which has pics of Juvies/larvae of every colour variation? (Yes, I did use the search engine and it turned out bupkis ) Or could we establish one?

Axolotl (Ambystoma mexicanum) - Embryonic developmental stages

This has a few pics of 3 different colored larvae at the bottom of the page.. hope that helps your collection.

Thanks !

i don't think the study of genetics is outdated, the formulas still work astoundingly, its just we haven't kept up with all the genes popping up to map them genetically yet, or their possibility. Instead of the 5 or so "recognised colours" there is probably loads more no one had considered yet, even if they are rare.
