Thinking it over again, what I first wrote might be wrong.
If one parent is homozygote fore a dominant (orange) trait all hachlings should show that trait.
The traits might mask each other, or they might enhange each other. You can not know.
The best testbreeding would be to breed two known
heterozygote:
Het dominant Buf amel X Het dominant Toffe amel
Then you would get about 25 % without buf or toffe
50% with buf or toffe
25 % with double trait dominant het buf+ dominant het toffe (extreme orange?)
If you got 75 % orange but 25 % of them look differen orange, then it might be different genes.
If you have two different orange dominant genes and one parent is het dominant and the other is homo for the other dominant gene, then all should be orange but 50% should be double hets for two dominant genes. Then there probably would be that half of the clutch would be different in the orange than the other half.
If you get no clear proportions in the clutch, but just a gradient of natural variation, then buf and toffe is probably just the same gene.
So, calculate proportions for the outcome you should get from what you know of the parents, if they are het or homo for the dominant genes.
Let the proportions guide you.
