What are the odds?!

Het is short for heterozygous. Het is the colloquial term for individuals that carry the gene for recessive traits.

"Het" means it is a recessive gene and the animal carries it but does not show it. So axanthic for example is recessive... It takes 2 copies of the axanthic gene to show but if the snake only has one it is then a het axanthic.

Thank you both! Understood.

Het is not just used to describe recessives. so that is not a good way to explain it.

Pastels are Hets too but they don't look like Normals...

Het does not necessarily mean recessive.
Hetrozygous just means it carries one gene. It may or may not affect phenotype. But even some 'recessive' Hets do look different from non Hets.

Homozygous means it carries 2 of the same or similar gene.

Examples:
- albino has 2 albino genes
- Het albino has one albino and one normal gene

- pastel has one pastel gene and one normal gene
- super pastel has 2 pastel genes

- pied has 2 pied genes
- Het pied has one pied and one normal gene

- butter has one butter gene and one normal gene
- Super Butter has 2 butter genes.
- Butter Mojave Leucistic has 1 butter and 1 Mojave gene. But since both genes lie on the same genetic loci, they do make a homozygous form.

Dam nikki know what she talking about ...

To answer the post question. .... ur only gonna get normals mojos pastels and pastave ...

If u wanna see if the het albino is there breed to a albino ... If u don't I wouldn't call none of ur clutch het for anything when u have it

Thank you for explaining further! Very interesting.

no, pastels are not hets. pastels are heterozygous for pastel, but they are not hets. they are pastels.

het is only used for recessives.

scientific term || every day term
heterozygous axanthic || het axanthic
homozygous axanthic || axanthic
heterozygous pastel || pastel
homozygous pastel || super pastel

if the homozygous form is called a super, then the heterozygous form carries the same name, just without super. so there are no super albinos, and no het pastels. if you say "het pastel", you strongly imply that super pastels dont exist, and that a breeding of a pastel to a normal would result in a clutch that is uniform and consists of het pastels, so it just doesnt make much sense. people will be reminded of the guys that try to sell normals as "het spider" on craigslist.

when you want to talk science, write it out and say "heterozygous". and only ever use "het" when its about a recessive. just like you only use "super" when its about a homozygous incomplete dominant.

[satomi325]

What the heck are you talking about?

Het is short for heterozygous regardless of recessive or not. People only use 'Het' because its easier to say or write than heterozygous. Het is just the short hand form of heterozygous. People still sell yellowbelly as Het Ivory and YB is not recessive.
Pastel is heterozygous for super pastel.
Super pastel is the homozygous form. So yes, pastels are het super pastels.

Normal heterozygous for albino is Het albino. The same as saying homozygous albino is visual albino.

So pastel and normal Het albino are both heterozygous forms. Super pastel and albino are both homozygous forms.

The name super is just a term made by Kevin from NERD. Its his made up term for homozygous.

Satomi knows what she's talking about.

There's nothing uniquely associated with "het" that links it to recessives, except for social norms between hobbyists.

The origin of the term has nothing to do with recessive genes though, but no, that doesn't mean you should call pastels "het", not because you're wrong, but because a large portion of the community you're trying to communicate with will be confused.

@ satomi325

going a bit offtopic, but to whom it may concern:


i agree that pastels are het super pastels, because here the het and the super somewhat cancel each other out, and its still understandable.

i have seen breeders actually sell fires as "het black eye leucistic" or as "het super fire", and i have seen breeders sell yellowbellys as "het ivory".

but can you give me cases where breeders advertise a pastel also as het pastel? or a yellowbelly also as het yellowbelly? or a spider also as het spider? or an ivory as a yellowbelly?

the actual use of the shorthand "het", in natural language, like on this forum and on breeder websites, is really limited to recessives. except for exception you pointed out, "het super XYZ". once you leave the scientific realm where language is really precise and delve into natural language, other rules apply, break them, and you sound like you are from mars. and actually you dont leave that territory but carefully avoid doing so in your own post which kinda proves my point

but now we are delving into linguistics. the method used to prove stuff in linguistics is really different from the natural sciences. to prove that a certain expression is used in a certain way, you start with a large sample of text in that language, search for all instances of that expression in the text sample, and check for context. searching the internet for the string ball python "het pastel" gives you one craigslist ad for a het pastel, a sentence that says "there is no such thing as a het pastel", a het pastel cornsnake, a het pastel boa, and a pastel het orange ghost BP, you get the idea. only 2270 results in total. that is quite a failure, with that data no linguist will challenge you when you say "het pastel" is not part of the english language.

now for ball python "het ivory" you get 15100 results, checking for context reveals most of them refer to yellowbellys. searching for yellowbelly ball python "het ivory" gives 11900 results, which confirms it, and shows that there is a contextual link. for comparison, ball python "het albino" gives 72700 results. of course these numbers are not worth much on their own, you need to sample the context of the search results and see if its actually being used in the way you expect.
