Strange Breeding Happenings

RandallRock · May 14, 2009

I just bred a few of my axolotls and encountered a few strange outcomes. Firstly I bred a Wild type with a Melanoid Albino a received an all-albino clutch. To my understanding it should have been a 50-50 ordeal right? Also I bred a melanoid female that in the past has only given me albino, wild and melanoid larva before with a melanoid albino male and what I received was leucistic and wild/melanoid eggs?! At least they appear leucistic. The white isn't as defined as in my other leucistic clutches and frankly some of the eggs look unlike anything else really, like a milky uniform Grey rather than a black. Anyone ever hear of this?

Thanks all
Aaron

The probability of getting albino offspring from 2 non-albino parents is 25%. But that doesn't mean that a clutch always adheres to probability. Just a fluke. How big was the clutch? A sample size of 20 is a lot different than a sample size of 200.

The milky grey is melanoid. Larvae and juveniles are rarely the dark black. Since melanoid is a recessive gene, if you breed two melanoids together, you'll get all melanoid offspring (either white, albino, or dark).

Google "punnet square"; it is a neat little tool for predicting genetic cross outcomes, however, like Kaysie said there are a ton of other factors that will determine how many and what colors make it to the all important "4 leg stage".

Truthfully, without knowing geno and phenotypes of the parentage a generation or two back, breeding axolotls can be a real crapshoot.

For example, my original breeding pair were a xanthic albino female and a leucistic male. They consistently threw albinos and xanthic albinos with a smattering of leucistics. Out of 13 spawnings I kept records of, only two threw wild types that survived past the first week, and only one of those had any wild types that made it to the four leg stage.

Thanks you guys. Kaysie, There is at least 500 in the clutch and every last one is albino. I also just mated the wild male in question with a lucy and got Lucy eggs so I have a versatile male on my hands.
sludge, Thanks for the info as well.

The Laws of Axolotl :
1. If it moves: eat it. If it does not move: gulp it up and eat it anyway.
2. If it too big to fit in the mouth, try any way. Then see rule number one.
3. All other animals, including other axolotls, are fair game if they meet the requirements of rules one and two.

This is FUNNY! & true!! LOL

I tried to say this in a visitor message but I kept getting an error...
