Due to the many reports and confirmation by breeders of both Mottled and Exchequer we have confirm that Mottled and the Exchequer pattern is based on the same mutation at the mottling locus, but due to the great difference of pattern I have come to the conclusion that it must be an allelic mutation of the mottling allele and for the purposes of this discussion, I use the fictitious symbol mo^e

Where Mo+ is the wildtype dominant(not mottled), mo is the recessive mottling mutation and mo^e is the recessive exchequer patter mutation and since mo/mo^e F1 crosses have shown an intermediate pattern(more mottled but less exchequers) one would say that both mutations are co-dominant to each other.

the order of dominance:
Mo+/Mo+>mo/mo, mo^e/mo^e

Mo+/Mo+ = not mottled all black
Mo+/mo = not mottled all black
Mo+/mo^e = not mottled all black

mo/mo= mottled
mo/m^e = intermediate pattern between mottled and exchequer
mo^e/mo^e = Exchequer pattern.

Source: https://www.ncbi.nlm.nih.gov/pubmed/3446343 (while the source indicates that pied(exchequer) and mottling are the same, no further test breeding was done so arriving to the conclusion that exchequer may be an allelic mutation of the mottling allele is in my humble opinion not an unrealistic proposition)

I would like point out that Early reports about the Erminette pattern(1940, F.B Hutt) believed that the Erminette pattern to be caused by a autosomal mutation giving it the genetic symbol Er(not to be confused by ER birchen), but later studies have confirm that the pattern is caused by Heterozygous dominant white based on a self black background (Homozygous Extended black with Ml/Ml)(source: https://www.feathersite.com/Poultry/CGD/Erminette/BRKErminBurroughs.html ) When the pattern does not breed true as two Erminette will yield 50% Herminette, 25% solid black and 25% solid white, for best results this pattern must be based on a solid black background, this means on a Homzygous Extended Black pattern and Homozygous Melanotic, any other backgrounds will likely not result on the same pattern and one can expect fewer black spots and ground color(gold, silver) leakage.

Austra White chickens(production type cross of Black Australorp and White Leghorns) these type of cross shows what early The Erminette pattern may have looked like in the early days, these birds are clearly E/e+ Ml/ml+ I/i+, breeding towards the black parent line will enhance the pattern.

I really like the Extended Black background on chickens as it lends itself to some amazing colors, I will keep posting on interesting patterns

Interesting.
I kind of like not the Extended Black but anything on the Dom. White locus fascinates me.
I love how white partridge looks on Wyandottes.

I really like this color, it's a shame that the only recognized breed with it is the Polish. A self Khaki based bird is a Homozygous Dun(I^d/I^d) on an Extended Black background(Dun based chocolate Orps should have quite a few Khaki Orps, but could not find pics of them on the web)

WC Khaki Polish pair:

WC Chocolate Polish, Dun based Chocolates are based on Heterozygous Dun(I^d/i+) Dun is an allelic mutation of the dominant white allele. if you breed two dun based chocolate birds you will bet 50% chocolate, 25% Khaki and 25% all black.

Here's the helpers list:

I just wanted to add that I know a lot about breed traits, like leg color, egg color, body type, comb type, etc. If you need any help with stuff like that.

We need all the help we can get

Cool I think most are working on the genetics of feather types right now. I'm sure they'd love your help.

If we had known this before I wouldn't have spent 4 days studying leg color. oh well, now I consider myself an expert.

I consider you one too, you sure can retain a lot
