Matttoadman Posted December 9, 2017 Share Posted December 9, 2017 So we have all heard of the in hobby cultures regarded/debated as hybrids. Blaberus fusca, Blaberus discoidalis, and several of the hisser genera. My question is, are any of these verified? We know assumptions have been made, but assumptions mean nothing in the world of science. So it seems the main assumption is that since there are no scientically identified examples of a particular culture it must be a hybrid. Since the culture has existed for many years and no fresh wild collected examples have been found it must just be a hybrid. There are many species of roach that are currently in the hobby that have not been identified as of yet. Eublaberus serranus was only recently identified yet had been in the hobby for years. No one ever debated its purity . This does not make them hybrids just unidentified. Has any actually tried to cross to proven separate species of Blaberus or Gromphagorhina to see if they actually will produce viable offspring that are not sterile? Are there variations between stock and within stock to give evidence of hybridization? For example, crossing two distinct species, expecially varying percentages, will produce varied genotypes. Sizes, colors, morphology, fecundity will all fluctuate. I have spent countless hours studying the results of wild gamefowl to domestic chicken crosses. The variability in the offspring is amazing. I think it would be interesting to begin an actual review of one of previously mentioned species. Recording all the information needed to verify a species. To compare different populations. From what I am learning genitalia is one of the main things that is used to distinguish one species from another. I think the members on this sight would have an accurate representation of the species to compare. Also actual hybridization trials would be helpful to dispel or confirm viability. Responsible dead end crossing could be done. So thoughts? Quote Link to comment Share on other sites More sharing options...
