From my rough understanding it is genetic traits that share an allele and only manifest when the other trait is present or in the absence of the other trait. It’s quite hard to wrap my head around, and without stable power I’ve sort of resigned myself to not having an exotic snake pet… probably ever, so it’s not something I’ve brushed up on lately. It is mainly something that python breeders use to manipulate colours and patterns or “morphs” in their animals. I don’t know if it at all translates to plants or non reptiles, but would think it might be something we see in chickens with penciling and lacing. Python breeding and different morphs was also quite big business at one point, with some colour patterns going for thousands of dollars before they became common. Bear in mind I also have zero formal education in any of this, just a lot of reading, some personal experience, and most of that is pretty rusty (but I do know there’s zero chance, if that lowland bull can even mount our Herefords and Angus, of him making the offspring bigger or faster growing, or even particularly better foragers of poor pasture

)
Ok please pose for the camera like nice chickens… mommy owes taxes! Lots and lots of taxes.
