Breeding Traits

[LeoGirl575]

I don't know if there is a thread about this already, but what traits rule over others?
So as an example; recessive x recessive = recessive.

I get all the terms, but I can never be exactly sure what I'm going to get from a breeding pair, because I don't know what rules over what.
Hopefully this question makes sense.

Thanks in advance!

I tried to respond but the message wouldn't reproduce my chart. Your best bet is to google to find out about basic genetics and read up on dominant, recessive and hets.

Genetics are difficult to explain quickly and you need to do some reading but it sounds like your asking which genes will dominate the others like brown eyes over blue. This is not the correct way to think of it. Traits work independently of each for the most part(some genes resting on a certain locus or location of a chromosome can effect each other). To make it easy think of each gene one at a time when figuring how they are passed on. The way each separate gene gets passed on to their offspring is described by recessive, co dominant, polygenic, etc. For example if a co dominant animal is bred to a normal, in theory 50% of the offspring should express the gene. Say the same animal showed a recessive gene and was bred to the normal type all the babies would be het or heterozygous(carry one allele for the trait). So when breeding this animal with two known traits to a normal you would get 50% with co dom trait and 50% would be normal and all of the offspring would be het for the recessive trait. Reptile breeders basically combine traits to create different morphs almost like a recipe. This is where the creativity it limitless. What they call these combinations just comes down to memorization. An example is a dreamsickle which is a combo of tremper(recessive), eclipse(recessive), enigma(dominant), and snow(co dom).

Hope this helps some. There is so much to explain that it is hard to sum it up so briefly.

Thanks a lot! Yes, that really helped! On the note of the dreamsicle.. they created it by breeding female to all of those other morphs?

And by the way, if I have a tremper albino het for sunglow, and a tremper snow not het for anything, what would I get? 50% tremper albinos, 50% tremper snows; but would they still be het for sunglow?

Thanks again!!

A gecko can't really be het for sunglow. Sunglow is essentially a superhypo albino and superhypo is a linebred trait, not a simple dominant and recessive. If you have an albino that has reduced (or absent) body spotting then it's likely that some of the resulting albino offspring will also have no spotting, but it's impossible to generate a percentage. If the albino in question doesn't have reduced spotting but has a parent who does, then some of the offspring will probably have reduced spotting, again, impossible to quantify, but probably less than the previous case.

Well an animal with as many traits as a Dreamsickle doesn't happen over night. To make it easy start off with the Raptor which is basically a combination of Eclipse(an eye pigment gene) and Tremper albino. They made this by breeding a Tremper to an Eclipse creating animals that appeared like normal leopard geckos but were het for eclipse and tremper. Then they bred the offspring together and only 1 out of 16 of the babies(in theory) should be Raptor(tremper eclipse). Now when you breed 2 Raptors together you get all Raptors. Next they would breed a Raptor to an Enigma het Raptor to create a Nova. Then breed a Nova to a Mack Snow het Raptor to create Dreamsickles. Now you can see how you can over time add traits into an animal.

As far as your Tremper Sunglow, what that means is Tremper albino(recessive) and hypo(polygenic) in one animal. Polygenic traits are the easiest to understand because they are line bred traits. Breed an orange gecko to an orange gecko and get an oranger gecko. So when you say tremper het sunglow that's incorrect. It could be that you have a hypo or super hypo(orange/yellow color and lacking black on the body of the animal) het for Tremper albino. If this is the case and you breed it to mack snow tremper you will get(in theory) 25% Snowglows(hypo snow trempers), 25% Sunglows(hypo trempers), 25% Hypo Snows het Tremper, and 25% Hypos het Tremper.

Good luck!

Wow, thank you! That helped a lot!! That's actually a good combination, and hope my pair breeds succesfully!

Here is a great morph page that goes into some depth about dominant recessive etc. for each morph. Hopefully it'll be helpful for you. http://www.paulsagereptiles.com/LeopardGenetics.htm

Thanks. I have read that before.
