I understand they're pretty complicated, but can someone help me with a few questions I have on them please?

1. Yellowface II is dominant to Yellowface I, is it receissvie to Goldenface?

2. What does a DF Goldenface look like? Does it have a white face like DF Yellowfaces?

3. What do you get when you breed the different types of Yellowfaces together?

Those are very good questions. I'd love
to know the answers to them myself, as
I have a couple of DF YF II, and I've spent
no little time trying to figure this out myself!

Here is what I've recently learned. The alleles (?) for green, blue, YF and GF all sit at the same spot on the gene. The order of dominance is: green>GFblue>YF2blue>yf1blue>blue

So, if you bred a light green bird (not split to blue) to a DF YF1 sky blue, for example, 100% of the babies would be light green split to YF blue. So if you then bred one of those babies to a blue/blue bird, all the blue babies would be YF blue because they'd inherit type 1 YF blue from one parent and plain old blue from the other. Make sense?
