Oh and to answer the Last two Questions (hopefully satisfactorially)...
The Cockerel is Golden Wheaten (or possible Salmon. I thing C=Golden Wheaten is more likely considering his sister) - Geno. e^wh/e^wh; S/s+
The Hen looks to be Silver Wheaten, and I can easily imagine her having a Diluter...
Sorry for inadvertently causing confusion... I did not mean to suggest that true black be called Gold Birchen, but I was trying to point out that some call it that, but calling it Gold Birchen is incorrect and causes confusion.
About Recessive black.. I should have mentioned that some believe...
Yes it would. Lavender does not mess around with the Pattern, but it dilutes both Color Types. So a Bronze Isabel would be Self Blue (mostly) with the the Gold areas diluted to the cream shade of Isabels. I don't think anyone has ever bred this color, and I'm not sure what Lavender would do with...
To answer a previous question, no, Co/co; E/E would certainly not have that much gold leakage.
And to add something to a statement above, Mille Fleur + Dominant White is Gold Necked. I think the reason she looks cream is, like Henk mentioned, DW washes out groundcolor.
True-Black (as seen in Stara fowl and Bow Lake fowl) with only one genetic change from wildtype (the E gene), look like Black Copper with yet more of an advance of black. True-Black is also called Gold Birchen (incorrect) or Bronze (correct). The Hackles of a cock are groundcolor, as are the...
Actually, Pheomelanin is not red, but Gold. Gold is diluted to red with an enhancer (making it darker) there are two Enhancers: Red (Mahogany) and Dark (Near-Black)
Wildtype pheomelanin has no red gene.
This always reminds me of an incredibly common error - 'New Hampshire Red' - Not only...
Basically speaking, there are three main Gold diluters:
Champagne - Recessive - the weakest of the three; hard to notice
Lemon/Cream - Recessive - dilutes Gold to a nive rich Buttercream color
Gold Dilution - Dominant - very Powerful. It can take Mahogany and dilute it to the same tone that...
Pretty good, but Blue/Splash is actually incompletely dominant.
There is no such thing as a 'Buff' gene. Buff is a combination of Gold Dilution (or possibly Lemon) and Mahogany.
Solid Buff (i.e. Orpington) is Wheaten, Columbian, Mahogany, Gold Dilution, and Chocolate Dilution (the tail)...
