I have a mottled genetics and how-to question, but will use the specific variety that I'm interested in to make my point. Does the mottled gene necessarily "stick with" other color genes?
If you have a flock of mottled lavender orpingtons. You breed out to pure black orp in order to improve type. The first generation would be visually black. When these were bred together, the second generation would result in 25% lavenders.
Would these 25% be MOTTLED lavender?
Or, by breeding these resulting lavenders (but not mottled) back to the original parent stock of mottled lavender, you would get mottled lavender.
I hope my question makes sense. Would either of these actually work the way I stated? If so, is it the shortest/best/only path for breeding out to improve type in a mottled lav?
