Guppy endler hybrid throw back

I have had my tank of guppyxendler hybrid for years now. I started out with one pure endler that my friend gave to me since he has an all endler tank. I had two young female guppies and when i put the endler the mixing began. Now is it strange that over the years my hybrids started out with many different colors but now look like complete endlers. Oh and all these years i have never introduce new blood. So they all decendants of the same 3 original fish. What i find strange is that they have become uniform and look like pure enlers and i do not do selective breeding i let them breed on their own. Has any one ever had something like this ever happen will they stay looking like endlers?

Genetics have a 25% chance of everything combination. Its possible that as they reproduced the Full Endler genes by chance graviated back to full endler and lost the genes for non-endler. I'd just go and get new fish of one sex to start the process over.

Well it would be like in a situation where they breed so much in a small gene pool that they are all inbred. This emphasizes genes, eventually most of the genetic variation would be similar but they will still be hybrids of the two different species of fish.
