Hi Jo-Anna! I don't think that it matters with insects but I could be wrong. I mean, after all. All we want them to do besides breed is to get there guts full and get ate so I don't think that it really matters how smart they are or whatnot . HaHa!!! No but really, I can't answer that 100%. I know that with my dubia colony, it probably has at least 16 different bloodlines in it because I purchased from 16 different people to build it. If you think that I can get them to you, I'll send you a batch of hissers when ours come in. That will ease your worries about having roaches that date their sister
