as to fire ants - diotomaceous earth may work
Now, exactly what genetic changes have been wrought in corns? All I can say for sure are cosmetic ones - colors and patterns. As far as I know, (unless someone is line breeding for size) that is all.I guess you're not aware of the scaleless corns then, or the fact that hybridization and or intergrades exist.
Color and pattern differences have already been weeded out by nature. Evolution/via natural selection is an ongoing and ever changing process, there is no foreseeable end to it, So speaking as if cornsnakes are at an evolutionary standstill is incorrect.Any interbreeding will result in wild-morph corns, who harbor these recessive color genes (don't forget Tessera, a dominant pattern gene). The odd-colored F2 babies will likely disappear quickly. These "genetic aberrations" being released will have a really tough time harming populations in this way, as the only ones harmed will be themselves as they are culled by every predator around - How can you possibly know this.The point I was trying to make with my examples is that we don't know what will happen, we just don't know and as has already been pointed out there are no specific studies to refer to. The only thing we can say for certain about releasing CBB cornsnakes is that we don't know what is going to happen and if we don't know then maybe we shouldn't do it until we do know.even fire ants.
Releasing captive corns is, in many ways, more like throwing food out the door. Along with any pathogens they might be carrying, possible genetic defects like kinking and stargazing and "invisible" genes that we may have unknowingly bred right along with them
Any survivors? Maybe, but this is where nature excels - weeding out the unworkable, keeping the good stuff. Maybe some of these morph combos will work out. If that were to happen then a scenario similar to the one I presented could occur.
As I said, I'd love to revisit the site in 20+ years.
The argument about the danger of introducing new genes, I think, is faulty in this case.Right we are not introducing new genes. We are selectively breeding genes that have occurred naturally, crossing them with other mutations, hybridizing them, intergrading them, and then breeding all of those to an unnatural proliferation until the animal only resembles the original wild type in a purely physical way. There are no modified genes, as in many plants we currently consume.
