I have Black breasted silver duck wings. American gamefowl. Concerning a full and upright tail. Do both sides contribute to tail form or does it fall to cockside inheritance under appearance?

It’s a polygenic trait (multigene trait). September 19, 2021 at 6:56 AM #14185 AnonymousInactive @ Thank you sir. Wasn’t sure. Both have good full upright tail. September 20, 2021 at 10:52 PM #14193 Kenny TroianoKeymaster @maximustroy2 that’s good. That should translate very well to the offspring.
