Umm...that part I don't have the answer to (yet). I just know what the color is. I'll get back to you on that.
Edit....
I don't know why the call the markings 'duckwing'...I could not find the answer to that. In genetic terms, it is a bird with the genotype of 'golden' (e+/e+, S/s+ bzw. S/-) or 'silver' (e+/e+, S/S+ bzw. S/-). The only difference between the two is the silver and gold genes involved. Golden is Ss+ and Silver is SS.
e+ = Wild-type coloring. Female: breast is salmon brown and devoid of stippling, body is black and brown in stippled pattern. Males: black breast and abdomen; non-black hackle, saddle and wings.
S = Silver (and Red-Gold.) Inhibits red pigment, pheomelanin. The expression of silver is sometimes affected by hormonal levels and is considered to be incompletely dominant and highly influenced by modifying genes.
s = Gold. Wild-type coloring, recessive. Invokes red pigment.
If there is someone who reads this that has a better understanding than I do, it seems that Partridge is the base and it's the presence of either S or s+ that make the difference in color, changing the red to either gold or white on the hackles, saddle and wings.
