Help on double het genes

[Spinnerman]

and would the chances be the same if i was breeding a pied het red axhantic het albino to a albino het red axhantic het pied? would i get 1/4 25% chance of getting an albino pied per egg?

I just wanted to point out that codominant and icomplete dominance are two different things. Codominance is when two traits are shown (you can see them both. For example, you mix plants with red flowers and white flowers and the offspring come out red with white spots) incomplete dominance is when two traits mix (for example, you mix a plant with red flowers with one that has white flowers and the offspring come out pink) sorry for using plants as an example but its easier that way lol

Actually this statement above is referring to 'classical' genetics, not snake genetics. When we refer to 'codominance' there is no mixing of visual traits to get a hybrid visual trait. Here are some 'cliff notes' on snake genetics:

Dominant: With a dominant gene there is no 'super' form. For example, if you bred a Pinstripe to a Pinstripe you would get 3 out of 4 pinstripes and one normal. The link to the genetics calculator is one I wouldn't use, if you plug in Pinstripe x Pinstripe it shows you get a 'super pinstripe'. This doesn't happen with a dominant gene (you'll only get supers with co-dominant genes).

Codominant: This is similar to a dominant gene except there is a 'super' form. Think of it as a recessive gene, but the difference is that it has a visual recessive, similar to the het red axanthic. Usually the super form is totally different than the codominant visual, such as a bamboo vs the pure white super Bamboo.

Recessive: Similar to classical genetics, if you breed a recessive pied to a normal all the babies look normal but all carry one copy of the recessive trait. You have to breed the babies together to get a visual (only one of four babies will be visual).

Allelic: This refers to two different genes that are on the same location of the DNA and act together as a single dominant gene to produce an unexpected visual that looks totally different than either gene. For example, if you cross a yellow belly with a Specter, both look almost exactly like a normal, you will get a 'super stripe' that has one copy of the yellowbelly and one copy of the Specter gene, looks totally different than either of the parents. Now if you start breeding using allelic traits things get interesting. They act like a codominant 'super' form but have two different genes instead of the same genes. So if you breed a super stripe to normal you get half yellow belly and half specter. And if you cross two super stripes you get super yellow bellies (Ivories), super Specters, and superstripes!

Super: Super is the results of a codominant trait having two copies of the same gene but almost always results in a completely different visual than the base form. If you breed a super to anything you never get a normal. For example, if you breed a super Bamboo to a normal all the babies will be Bamboos. And if you breed a super to a super you get all supers.

Confused yet?



I would suggesting using this genetic calculator, it's pretty close to being perfect:

Yes, het is short for heterozygous. Heterozygous means it has one allele and therefore het red axanthic is fair to say. Technically fire, Mojave, pastel and every other "codominant" gene is heterozygous for the super. However I feel like trying to explaining this to someone who doesn't understand genetics would only complicate the issue. In every other case (as far as I know) we only say het for supposedly recessive genes. Based on the communities terminology het red axanthic is a misnomer.

Yes. Why do you keep asking the same questions over and over again? Please take the time to learn and use the tools shared in this post where the exact same quesiton was asked: https://ball-pythons.net/forums/show...=1#post2505949.

I think someone actually messed up when they named it 'het red axanthic'. Perhaps initially they thought it was a recessive trait, then realized it was actually a visual het. Perhaps it was named that way for so long they stuck with it, but it should have been listed as a co-dominant gene using red axanthic and super red axanthic.

Don't get discouraged, I used to ask the same things over and over when I first started. The genetics can be very confusing. I used to sit all day in front of the genetics calculator for weeks on end before I finally got it. I found that it helped me to put a dollar figure on each baby snake and think about the market and how well they would sell, that way you can optimize your breeding for maximum dollars and sales (if you plan on breeding). Most big breeders like to have a lot of mid range or low end snakes with a few high end snakes, the low end is their 'bread and butter' since that's what most people can afford as a pet.

Oh - I don't get discouraged (easily) by variations on the same questions by someone who is learning. I wouldn't be able to be a Mod if that were the case! This is different, though. It is literally the exact same question with the exact same genetics being asked in multiple threads.

Ok im sort off starting to get it now so the het red axanthic is not a het but it is simalar to a heterogeneous gene except from its visual? And thank you to everyone that has helped me in this thread.

I can clearly remember my first NARBC snake show and asking about genetics for the first time, the snake guy behind the counter said, 'your not very smart, are you?' LOLOLOLOL

Well... are you?
