Genetics 101 question concerning recessive traits.

rujonesin Feb 29, 2004 10:06 AM

I know that BD's can carry recessive genes as we can look at the leucistic dragon for that. I am seeing people selling dragons that are "het" for hypo. Are any other genes carried recessively? I know in snakes the hypo gene can be carried recessively but is it in the dragons also? An example question. I have a male that had a hypo mother and a snow father. He looks very much like snows that are being sold now. If he was bred to a sister from the same clutch, what could you expect from the resulting offspring? This question is for making a point only so don't beat me up on breeding siblings. I honestly believe that inbreeding causes smaller, weaker animals in the long run. Any genetics comments at all are appreciated. The dragon below is the one with Hypo/Snow parents. What are your thoughts as to what it would be called? A snow? Hypo? It does not have the clear nails.

A hypo/snow is not always considered a true hypomelanistic. These guys just come from lighter colored dragons that produce whiter and whiter dragons as the generations go on. They are not a hypomelanistic trait because if you breed a hypo to a normal, you just get a mix of lighter dragons and some darker ones. True Hypomelanistics have clear nails and cant show as dark color as normals. These guys, when bred to a normal, would produce normal looking offspring without clear nails. These hets, when bred together would produce 25% hypomelanistics and the rest hets and possible hets. A hypo is pretty much the same as a snow. But a Hypopastel with clear nails is a true hypomelanistic. The hypos and snows are also proving to have a codominant trait so if you breed it to darker animals, you will get lighter babies, that is why poeple started to breed Sandfires to Snows to get less black color and more red to show. By the way, I don't want to make anyone mad, but I don't think the Leucistics are true Leucistics. I won't go into explination unless someone wants me to because I don't want to make anyone mad.

Please by all means expound on your thoughts concerning the leucistics. I am trying to get a complete comparison on how the genetics in boas and beardeds compare.

I agree, please go on. And anybody else with genetic info. I would love to see any findings on dominant, codominant, and recessive traits. Also hybrids. PLEASE!!!!!!!!!!

Okay but believe me I am not by all means insulting Kevin Dunnes animals, I have bought an animal from him and it is fantastic.

The leucistic dragons seem to me be only a form of the Hypopastel clear nailed dragons. They just were bred get all of the pinks and yellows out of them so they turn out white. If they were true leucistic, they would have black eyes, they would be patternless from day 1, and they would not be able to black throat because they don't have any black pigment. Plus, the main reason I believe this because of Rob and Vickie Dachiu's breeding of a Hypopastel X Leucistic. If the leucistic was a different trait compared to the hypopastels, they would have gotten double het animals because they are two different traits. But, they got just hypomelanistic animals with great color. Then, they bred and got hets for the leucistic, bred that to a het for hypopastel, they still got hypomelanstic animals from the hets. That is what makes me believe.

Actually no we can't. There is no true leucistic in bearded dragons, and the only two confirmed recessive traits are albino & translucent.

So what's everything else???? codominant??? There have got to be some recessive traits out there.

Mattman Feb 29, 2004 05:54 PM

Don't forget the clear nailed hypomelanistics Axe. They are confirmed by quite a few breeders now. They are recessive and breed recessive just like translucent. Albino I haven't a clue as i've seen nothing but pictures from other countries claiming albinos. I assume though they would be recessive as well though.

Thanks Mattman, I wasn't 100% sure whether that had been undeniably confirmed or not yet. I haven't checked on it in a while - but I had assumed it probably was. Now I know

Don't forget the clear nailed hypomelanistics! FYI
