I am going to assume the actual translation here is what % high quality F1 can be produced by a high quality pair. In my experience there are always going to be a small percentage of culls with defects (gill plate, fin, twisted mouth, etc). F1 raised in safe domestic environments generally will all grow up with nice shape and color with proper care. To define high quality F1 you'll have to specify what you are looking for - shape, color, pattern, etc.
2.what % of F1 royal blue can produce a wild royal blue pare?
If you have two royal parents you will end up with greater than 50% F1 with royal pattern
3.a good quality pare can produce homogeneous discus or produce a lot of diferent discus in the same batch?
Remember, most wilds in the brown, blue, and green varieties the highly patterned fish are usually the dominant males with a few exceptions of dominant highly patterned females. So normally a pair of wilds would be a royal/semi royal male and solid female. That is what I have usually ended up with and the production is heterogenous. 25% solid, 50% semi royal, 25% royal pattern. With spotted fish like the RSG, you'll also get a similar distribution of very little spotting, most will be mid level spotting, and the 20-25% that will be highly spotted
4. can a "low quality pare" produce high quality F1?
I believe as long as the 'low quality' is not genetic and environmentally produced a 'low quality' pair will still produce a percentage of young that will be highly patterned and 'high quality'
5. can a solid color wild pare produce F1 with patterns?
Yes, solid wilds can still come from parents that one or both had striations. The fish can carry the genes for striation expression
