I see you are active on this forum. I bought your book on mutations and genetics
last year.

I want us to discuss the issue of the Orange Redrump again. My breeding results
indicate that it is a true recessive mutation. I have bredt Visual Orange birds
from split pairs showing no Orange at all. The Orange are obviously more bright
on the Opaline birds, because they have more Yellow naturally.

What pairings and test do I have to do to prove this.

A few pointers from all your experienced people.

I include a few photos in A Paul's Birds.

Thanks
