No, phenotypically it looks like a Yellow Golden, genotypically it will have the Red Golden genes also. This is why it's important not to crossbreed, because you get birds that look 'pure' but they are not, and when sold as 'pure birds' to the unsuspecting buyer, they think they are pure and breed them, and sell the offspring, further diluting other 'pure lines'.
Yes the darkthroat, cinnamon, yellow, and splash goldens are all documented to have come out of pure birds. The peach, flame, and silver are all unknown but since the silver golden mutated out of yellow goldens they're a safe bet.
I talked with James pfarr about the genetics behind silver vs. yellow and he thinks they're just a dilute form of YG's So to have a silver you'd need to either breed to another silver or a YG carrying the dilute gene.
Along those lines, I have several Yellow Goldens (juveniles) that instead of the dark brown/black feathers on the back, they are laced like the cape feathers and the same color as the cape....I have no idea where it's coming from or from where it would get that coloration/gene? None of my parent stock have shown it in their offspring until now, some of the birds are 11 and 12 years old.
