I will try to get him on here. He one an award at the last IRBA show for them. I believe he is the only one that is working with those. He breed his bright yellow male to a very nice, yet normal female. The babies seem to come out all light, bright, yellow. The dads genes seem to be dominent. He produced a baby this year that is going to turn out insane! The yellow male, and the babies have much lighter eye color too. Anyways, it is still towards the early stages of this project, but it is genentic. I can't wait to see what he produces this year!
