This is ow a breeder creates their own line. My fried used to breed mollies and one time she bred in an electric blue male and Somehow all the fry got an electric blue tail so he added his original breed name for them because he is the first to create it (in a different form anyway.)omg so pretty and geno means it might not have a certain gene physically, but in her/his blood there is a certain gene, so is that betta ever spawns it will have the specific gene into the fry (physically) that happens with a DBT gene a lot
Really interesting if you ask me!
Though sadly this does happen often with DTs physical features.
