Marvin,

Note that they are birchen based, which also flattens gold groundcolor a bit (imo).

Hmmm, I'm working with a theory, that it can be totally opposite. I have posted some pictures on November 02. in this thread.

If it is assumed , that there is no Mh in them, what can be the cause of the darkening of the gold in the hackles?(any potential 'red enhancers' were already in e+ birds)

How is it determined that there is no other dilution present? And in either case, the dilution is not nearly as much as lavender dilution. How do you account for
or

Blue will not make the red/gold any darker (optically), that's for sure.

Does anyone know, whether blue and lavender are a derivate of melanophilin on Chromosome 7??

It is a little bit confusing, what I can find in WWW.
Blue in dogs, cats and mice (I have to guess, that it fit to blue chickens aswell) is due to melanophilin. (Or is the blue of coated animals rather comparable to lavender?)
And lavender in chickens, is also effected by a SNP of melanophilin. So is there a mutual origin??

Sonoran Silkies asked: "How is it determined there is no other dilution factor present?"
My reply to that would be: Thirty some years of experience breeding wheaten and blue wheaten. When you cross the two varieties you get about half of each. The red in the blue wheaten siblings is always at least a shade or two lighter than in the wheatens - both male and female. It is most noticeable in the hackles. The same empirical evidence was noted when mating Blue Laced Red Wyandottes with Golden Laced though the difference was not as pronounced. The red was a deeper shade in the Golden Laced siblings. The two pictures used to make your point are comparing apples with oranges.

Redcap, there is an information about it in this thread(October 29, posted by Black Feahter)

http://www.the-coop.org/forums/ubbthreads.php?ubb=showflat&Number=88951&page=3

Chromosome 7
- Lav : MLPH (melanophilin)

Lav is comparable to blue in dogs, leaden (not the D-locus) in mice; so mammalian D-genes differ... wink

Yes, i know, but blue is also called simultanously with melanophilin. So what says us that?? Is blue also on chromosome 7??
