do you have a clue what alleles are?
Like many genetics terms "allele" has some slightly different usages. I agree that it can be used in the broad sense of any gene location. However, if you google it you will also find it often defined as one of the different forms of a gene that can exist at a single locus. That's how I first became familiar with the term when it was proposed that the corn snake mutations Striped and Motley might be alleles in A Color Guide to Corn Snakes in 1991 before the two mutations where ever crossed to put it to the test.
If this was the case with Pieds and Clowns I could produce a Pied by breeding a Pied to a het Clown.
SORRY, DOESN'T WORK THAT WAY!
That is what I'm asking. Has anyone done this cross to know if it does or doesn't work that way?
Years ago I saw a post where Matt Turner produced an unexpected piebald from a clown project. Unfortunately I don't remember the exact details and have never heard any follow up results of future breedings. I think he was using a het clown male but I don't remember what the female was (suspect it was a presumed normal selected for belly markings).
I'm not saying it's extremely likely that pied and clown are different mutant alleles of the same locus but it's a possible explanation for that one breeding that as far as I know has not yet been tested and eliminated.
The ONLY mutations in snakes that have been shown to have the same allele for TWO DIFFERENT PHENOTYPES are Stripe and Motley CORN SNAKES.
There is strong evidence (but not yet ironclad proof) that Lesser, Mojave, Phantom, Vin Russo High Yellow Lemon, and perhaps even a theoretical dilute gene that combines with Lesser to make a Platy, and possibly also whatever combined with Mojave to make the Crystal Ball may be a huge multiple mutant allele group in ball pythons.
Please DO not post information that is not FACT based, it doesn't help people that are trying to learn.
I strive not to post incorrect information. However I think public forums are a great place to hypothesize and then discuss get to the more interesting and obscured facts. Sometimes people will get confused with technical discussions but at least the ones who want have the opportunity to learn and contribute to the fledgling knowledgebase of this hobby. I don’t write the general readership off as not being capable of understanding any discussion with the proper explanation. If more people are getting confused than learning then we just aren’t doing a good enough job of explaining.
