markers

Are there any markers in a normal bp that might indicate it could be a het for something

If it's codom then it will be something like a fire or a pastel, those are het. If it is dominant then it will show up, and having hom would look no different. if it's recessive, which is probably what you mean, then no. That's kind of the definition of recessive. You can not tell that it has specific het genes, otherwise it would be a codom.

There are some mutations that don't seem to fall neatly into the recessive or co-dom categories and appear to have sporadic visible hets. In ball pythons piebald seems to be this way with many (some estimates as high as 80%) of the hets having a clear lower belly with dark solid stripes at the edge which looks like the pied pattern starting to develop. The problem is it varies in quality, not all hets show it, and some non hets show something similar. But to show up as often as it does in het pieds it does seem to be a co-dom tendency of the mutation.

There have been less well documented rumors about other "recessive" ball python mutation that might show in some hets but piebald seems to be the best example so far.

I have 5 het Albinos and 4 of them have atleast 1 yellow (albino) scale. Call me crazy but that is 4 out of 5.

My female has one white scale in the middle of her brown(her grey spot)and further down the same thing

Well if you don't know what it is, try breeding it to different things to see if you can get something.

Oh I know what they are, they are het Albinos and they all came from realiable breeders. My question is, could those scales be "het Albino markers"?

I was talking to redsman O.o

Every single het Pied I've produced over the last 4 years has had the belly marker. So if anyone has poss hets or is looking to buy them, I'd recommend getting ones with the marker. If you have ch animals with the marker it doesn't mean they're het pied. I've bred 4 ch females with the marker and none have produced pieds.

I have heard several descriptions of the het pied marker, and have even seen a pic or 2, but wasn't completely sure what I was looking at. I did have a friend produce possibles from a het x het pairing (one visual produced), and they all look to have what I understand to be markers. Could you post a pic so I can be sure of what I'm looking at?
Thanks.

Here is a possible het pied male I'm using that passes his three scale wide white belly with thick dark lines on each side of the tail to about half his offspring. Most het pieds aren’t as extremely well marked as him. He was given to me as a 25% chance het but I’m told that all of the similarly marked animals from his line so far have proven including a sister that produced a very high white pied to knock this guy up to a 50% chance het on paper.

And her is a keeper daughter of his from this year:

well im not new to balls but in the boa world it is true that het markers exist but this then (as stated) throws the big question are such things like pied ''recessive''?
wouldnt a seconadry stage make these animals an incomplete homozygote?

In Burmese Pythons some het Granites have the Puzzle pattern that is sort of intermediate between normal and Granite. Also some het Green's have an intermediate pattern between normal and Green with the space between the dark blotches being not being as much smaller than the blotches as usual (I forget what they call this, cinnamon?). But the thing is both are only seen sporadically and there are also some normal looking hets. I think the concept of fully recessive is a nice text book concept that does fit some mutations well but maybe there are some "recessive" mutations that didn't read the text books and have these sporadic co-dom tendencies. Not sure what the text books would call that though.
