What Makes What and Het Info

I'm trying to put together a little guide of morphs for myself so I can understand this stuff, so I was wondering if anyone could possibly direct me to a site that tells you what the morph is, whether its dom, reccessive, co-dom, what two snakes you have to breed to achieve it, and any information on hets.

I don't quite understand the genetics of snakes. Supposedly, I have a 100% Het Pied male. How do they know its het? If it is 100% Het does this mean they bred two pieds together so it is a sure thing that any normal looking offspring would be 100% Het. What does 66% Het mean? I know there are more % Het but if someone could explain.

As far as a resource to learn what you have to breed together to make designer morphs, the BEST source is one you have to pay for:

As far as simple recessive genetics (which is how Pied works), I wrote an article quite some time ago that might help:
http://redtailboa.net/forums/how-tos...t=genetics+101

That should explain what hets are and where those pesky percentages come from. If not, post here again and I will do my best to answer any specific questions you may have.

Incidentally, to answer the most specific question from your post: if your snake is 100% het pied, that means that ONE of it's parents is Pied. The other parent could be normal or het, but for it to be a 100% het, one had to be a pied.

Because you should have purchased it from a reputable breeder with a genetics guarantee.

It was only my second reptile expo ever. I don't know who's good and who's not. I actually went with the mindset that I wasn't getting another snake until December, but these two babies caught my eye. Next time I will make sure to seek out a breeder I know to be good.

So true. But would be awesome to know if you bought a normal to prove out its a het.

Heres a good site, but doesnt answer your question. Maybe someone else might run into it and might find it useful.

Im still trying to understand it too.

Thanks for the link. It definatly helped me understand hets a little more. I get how the outcomes work now. :D

Oh and rabernet, I think you took my question the wrong way. I was asking how they knew the snake was het, meaning I was wondering how you could tell a ball python was het for something when they have normal markings. Now that I've looked over the information provided, I know that if the breeder bred a homozygous individual with a het or normal, all offspring would at least be het for the trait, therefore having the 100% het put it front of its name.

Ahh, gotcha - I think I did read it wrong. I thought you were asking how did YOU know that yours was 100% het.

Nope. And if it turns out that Xefaud is not a het for pied, then I still love him all the same and I will purchase a het from another breeder that I have researched. I've already started looking at some breeders that sell online. 8-Ball, for one. My fiance said I could get another ball python as soon as we got our own apartment, so I'm saving up my pennies!

Hang on, im trying to learn as i read this too...
If you set up a punnets square, say with a Het for albino, and a Normal, the offspring will all be Het, none of them will actually be albino.. right? So if one was to invest in a 100% het for albino, in order to produce albinos, you would have to breed it with either another het, or an albino, correct? Bred with a normal will only produce more hets? ...i think... :confused:
