I don't recall there being any proven simple recessive genes found in cresteds yet. Everything seems to be co-dom/dom. I think its interesting that even though an offspring can look nothing like its parents, that the third generation has proven to carry the grandparents influence. Hereditary traits of the rhacs are definately not as clean cut as balls and red-tails for sure, which makes it very mind boggling, and dare I say "fun" for those who love callenge and thrive to make sense of it all.

The truth can only be found in proving this "pieds" offspring. I am hopeful it proves just as I am that the trait is found among other rhacs. If I could find this trait in my gargoyles or Nuu Anas, I'd be dancing something serious!
