OK - in the Sigi/Hancox basics book, on page 18 and 19, it shows a silver breasted female duckwing....(the creations of exhibition lines)
It looks to attribute the salmon breast to Ar+ seperate from e+ ?
if not, what makes the silver breast in an e+/e+?
I just had a silver breasted silver female duckwing show up here. The silver breast shows up when autosomal red is not
present. It appears when only the e+ and S/s- are present, thus e+/e+ S/s- ar/ar. Wildtype in the truest sense (e+/e+ s+/s+) is the "bottom line" as far as color is concerned. There are no hypostatic genes in it. No mutations. No extra genes. Wildtype in its truest sense (e+/e+ s+/s+) is the base upon which other genes and modifers act to make all the other colors in poultry. Ar+ is a color which changes other colors. Wildtype is naturally salmon-breasted. It is part of what it is. I was warned by those with much more knowledge than myself that figuring in Ar* in breeding wildtype would be a mistake. Everything isn't yet known about Ar+. Thus, I was told figuring it in a breeding program as if it were a known and analyzed gene would be a mistake. After seeing how it sets itself in a breeding program and the mess it can make in wildtype with 2 doses, I believe it. I was warned that once AR+ sets itself in a breeding program, it is hard to winnow out. Sadly, now I believe that too and have had to go out to another strain to get non-Ar+ wildtype Marans to fix the problem.
