They call that an F2 when wipers and white bass back cross. It is happening at Horsetooth. You end up with really big white bass;DWhite bass as everyone said. Wipes have a more elongated shape and darker, more broken stripes. Only sure why to know is the tooth patches on the tongue. One patch for white bass; two for wipers. And even that can be tricky. Wipers can breed with white bass and become so mixed that it can be hard to tell them apart. Wiper on wiper breeding cannot happen.
