Genes of this rooster?

[Deo]

I came across a very bright (and extreme) diluted (by the looks of it) rooster while going through some posts. What is causing the diluted pigment to be so bright and what is this pattern called?

(Also, how could one replicate it? What breeding stock would you use?)

 

[sylviethecochin]

I see birchen (Dominant to everything but extended black), mahogany (D), a gold dilution gene (there are several he could carry, but two of them are dominant) and black (recessive). You could get that bird from most combinations that contain those genes, since most of them are dominant.

The first cross that occurs to me is a Gold Birchen and a Cream wheaten

For that particular boy, I'd say multi-generation mix because of the very small crest and rose comb.

The brightness is just the lighting, mostly. The white sheet in the background is just as light.

Thanks! I thought birchen too but wasn’t too sure. However, with dilution genes doesn’t it also dilute the shanks and skin? He seems to be a mulberry in terms of skin color which is odd to me.

I was pretty sure it doesn't, but I wasn't sure, so I checked Edelras. The site says nothing about Di or Cb (dominant dilution genes) diluting skin or shank colour, though it notes several other characteristics of the genes.

The Sex-linked Silver gene (S) changes most of the pheomelanin (gold-red) of the wild type phenotype to silver-white, except for the salmon breast of the hens. This gene is incompletely dominant in the males.



Di (Dilute) characteristics;

*note, the above pheonotype is an accumulation of columbian-like restrictors (eg, Co, & other possibilities such as Di, etc)

• -incompletely dominant
• -dilution of pheomelanin in adult plumage (gold-red)
• -dilution of chicken down (in pheomelanin),
• -reduction of lateral stripes on wild type down (stripes remained in the head & eye area),
• -dilution of dermal pigment (id+), &
• -a partial eumelanin restrictor.

Cb (Champagne Blonde ) characteristics;

• -dominant
• -might have a close linkage with Columbian,
• -not supposed to dilute down (pheomelanin) &
• -no change to down pattern.

That was informative, thanks. Perhaps it was the recessive cream gene (ig or something) that does that. I swear reading that somewhere.

I wonder if it would be possible to do matings with a wildtype bird to isolate these genes since they seem to work differently.

I see a duck-wing pattern(Brown/Red Wing Triangle) if it was a Birchen the wing triangle would have been completely black.

example: Duck-wing on the left(BBR), Crow-wing on the right(ER gold based: Brown Red)

I also believe that he may be gold based diluted(e+/e+, s+/s+, ig/ig) You can see his wing triangle of a dar red color, had he been a true golden(S/s+) the wing triangle would have been silver instead

I found the relevant information [concerning ig] :The gold diluter has no effect on id+ slate/blue leg colour, and appears to be a recessive gene.

Maybe you were thinking of barring?

Whoops. I'm used to a much more blatant triangle.

Light Brown Leghorn, as with everything the shades within the color will vary with red enhancers or lack of them.

Also if you look at his eyes, beak and shanks they seem to be showing an effect of Fibromelanotic, and a crest perhaps he is a Silkie cross rooster? I did a search on this an came up with this rooster.
