I absolutely agree with and understand not releasing them, and that if they change owners it should be known they are hybrids. But why should they not be bred at all? Does crossbreeding never happen in the wild where different garters exist? Would they even be able to breed? Is crossbreeding known to cause problems, or is it just a concern for muddying the gene pool?

Sorry for all the questions, but ever since I read a passing remark about hybrids in a thread here, I have been curious. This post roused that curiosity.
