How do u create 100% hets i thought that they would just be 66% hetts

If you have an animal that visually shows the trait (albino) and they are in the pairing, dame or sire, then the offspring of the litter are 100% hets for that trait. If you take the 100% het animals and breed them together you will end up with a litter of scrubs where some will show the trait and the rest of the litter will appear normal. Those normal animals are 66% hets, because some will be and some will not, you don't know which until you breed them and prove them one way or the other. I have a WC albino radix, last year when she was ready I paired her with a very high end red radix. 28 scrubs in the litter, all 100% het for albino. They will be/are the base for my breeding stock, and when paired together the litters will produce albinos, maybe some red albinos, and 66% hets. This will get this WC girls genes out into the hobby and a new bloodline of albino will be available for the hobby to work with. Again for gene related questions look at Jeff Benfer's website or older threads when he has broken this topic down, it really helped me to understand it. Not near as well as I would like yet, but I'm learning, it's a journey! ;)

when a visual trait(that's recessive) is bred to anything, that gene is passed on to all of the offspring and we call those 100% hets or just hets

Also , if both parents are recessives the offspring will be double het and most likely visually appear as normal. In most cases.

Does anybody have a link that explains how all this genetics works and what all the terms mean?

What about male and female that are both double hets for snow

just think of them as het anery and albino which is what creates snow. you will get anery, albino, snow and normals

Punnett Square Calculator | Science Primer (http://scienceprimer.com/punnett-square-calculator)

use punnet squares to get percentages and possibilities of outcomes

And idk but it might be that you can get a possible 25% of each of the offspring out of those double hets. Like 25% normals, 25% anery, etc.

when i did my pairing of double het normals i got more albinos than anything and only one anery lol more than half were albino few snows 3 normal and 1 anery theres alot of variation so i only go by what morphs willl come out lol i dont really worry too much about percentage until they are born

Albert Clark
07-19-2015, 03:49 PM
Actually the percentages can vary and idk if it's 25% or 12.5% of the possible production.

you can do the same pairing every year and get different results each time ahaha the thing that dont change is morphs produced

Tommy love that you added that link for the PS Caculator, I'll get to reading that and try to wrap my brain around that. Does anyone know is there also an existing chart where one can go that tells you what the genes are for garter morphs? Like what does a straight normal red radix look like? Then what would it looke like if it were het for albino or axanthic? What if it were normal but dbl het for both albino type?

in my experience hets look no different than normals they typically look like one parent or the other. the most detailed description ive read on garters is on jeffs site but i have a book on genetics i refer to its called "genetics for herpers" by charles pritzel

forgot to add that if the parent is a morph like a snow 0r albino the pattern/coloration will look like the gene pool it descended from lol garters have a variety of polymorhism so in most cases you will never be able to tell visually if a snake is het or not for a recessive trait cause all your seeing is the wild type gene expressed

That depends on what you are pairing up first. Then the odds gods come into play and put their 0.02 cents in. Thirdly, genetics is not a absolute science and there are always unknown variables like retained sperm, any genetic het variables.

You will be able to see subtle differences in some offspring. There may be a different coloration shade like a lighter phase or you may see a reduced pattern in some that can tip you off that the animal may be het for another mutant gene. However , mostly het genes have to be proved out.

retained sperm has nothing to do with genetics lol if you only pair one female with the same male every time

and in all my pairings i have never been able to tell if any snake was het or normal the mutant gene is not expressed in hets which is why it is a het and not the morph
if you breed 2 dark radix together that are het albino the normals will still be dark and albino look like albinos only variations ive seen is pattern

Tommy I know hets look normal, I should have used another word, what I was asking is that in order to use the Punnet Square Calculator you have to have something to plug into the square and what do examples of the genes that the animal carry look like? Like Jeff on his page when he used an albino as an example it was represented as aa, where as a het normal type was Aa, does everyone use these two or he just made them up? Like for the square could an axanthic be represented as xx, where a het normal (for axanthic) be Ax? A dbl het normal type for albino and axanthic be AaAx? Or like you pointed out think of a snow as being a dbl het, for anery and albino, so in the square what does that look like? AaAan, the Aa being het albino gene the Aan being the one for anery? That is what my question was about, is there a chart somewhere that is established to use for the PS Caculator for the different morphs in radix or eastern or whatever or do people just make up their own system as long as you know what you are representing. Was that confusing? :)

Because what I would like to do what I would like to figure out at some point is producing red radix that are het for both albino types and then possibly as a bonus the offspring of this pair could also produce Christmas as well. So using the PS calculator I'm trying to figure out how to get there. The other animal as pairs that would be cool to have in a collection (to me) would be a normal/wild type radix but was a multiple het animal that could produce both albino type along with anery and snow. So a powerhouse of an animal which when looking at the clutch it was just a rainbow of morphs in one litter. Don had an animal (Cariad??) she was/is the mascot of the forum, but she was an animal that as a normal/wild type she was het for multiple kinds of morphs. And what I always thought I saw in her (maybe just me) but if you go back in those threads and really look at her in the pics, you can almost see in her scales these little individual scales that are red, black, white, like she was telling you I unlock all this stuff. Now I'm rambling, but how did this snake come about? Was in purposeful line breeding of certain animals over years of projects (which of course it was) but knowingly, or dumb luck?

look at scotts site under price list and look at quad hets
i just sold adult red radix that were het for both types and still have a pair i picked up 2.2 from scott

to produce quad hets that are red you would need a nebraska snow and a iowa snow both from red parents and breed them together which will produce all normals. about half will show red then when you breed those offspring to eachother thats where the magic happens lol

Dan72
07-20-2015, 12:33 PM
Nice to know Tommy, thanks! The 2.2 you have from Scott, they are something you are keeping for future breeding down the road? I mean I know eventually the easy thing to do is if you want snows then get a pair of snows and bam, whole litter of snows, no guess work. Same goes for anything blizzard, axanthic, albino, whatever. But I just think the coolest thing is to have a pair of animals that when you breed them to each other you get a bucket full of different stuff. So I just need a pair of snow or blizzard. Breed high red examples to them to get my high red hets. Keep all those animals to in turn breed back to each other, then I will end up with snows and blizzards who are then also het for other things? Now I'm confused ;). Arghhh! I'm just going to keep breeding things into things and never part with anything, (kidding). Not the breeding, just the non parting of things.

when the 2 different snow types are bred all normals are produced. you will not get morphs from the first paiting you will get all quad hets that are het for iowa anery iowa albino nebraska anery nebraska albino. the two types are not compatible to produce morphs on the first breeding only offspring will produce every morph the genes dont line up until they are mixed if that makes sense lol

you get 1/4 albinos, 1/4 anerys, 1/16 snow. that's how its broken down in the most basic form

from breeding double het to double het i ended up with 11 albinos 6 snow 3 normal and 1 anery lol

is that the norm...when someone is just learning about genetics you have to start with the most basic knowledge, all of us experienced breeders know its not an exact science but you have to learn how to crawl before you can walk

i referred him to punnet squares then i told him what (i) produced from that pairing
