Color genetics

Barring has not been accepted yet, but some people are working towards that, the big issue is that they lack slate shanks, the females may have dark shanks but males don't here is a pic of a barred ameraucana project pullet from years ago(not mine, don't know how the project has evolved) View attachment 1729320

and the thread about Barred Easter Eggers(That look very much like how barred Ameraucana should look like)
https://www.backyardchickens.com/threads/barred-easter-egger.94095/

This Ameraucana looks like an overgrown version of my d'Anvers hen Impasta. The resemblance is uncanny. (The legs aren't yellow, just pale, probably white! I may have accidentally crossed a d'Anvers with a Dominique unknowingly.)

Actually, looking at the two pictures side by side, I think Impasta's barring is actually pretty nice and light, except for the smut on her wings.

the reason behind the lack of Dominant White on breeds that call for Slate shanks is because dominant white will greatly dilute the shank pigmentation, in birds like Ameraucana and the bresse breeds they are based on recessive white

100% agree with you .

Red Pyle perhaps? It can be done with Splash instead(substituting I/I with Bl/Bl on a Black Breasted Red), Pretty much any pattern that calls white portions(except self white as splash on Extended black can't really produce all white birds) can be substituted with Splash if bred for.

I m not sure what are you trying to say about a Dominant white I/I could be substituted by the Splash BI/BI .
they are different genes and produce different pattern .

I m really interested if you can go in more detail please .
I work with a dominant white, Recessive white and Splash { Marans chooks }.
Thank you.

Sure no problem.

Most people experience with Splash are with self Blue/Splash breeds, basically self black birds that have been diluted by blue/splash(Bl/bl+ or Bl/Bl) in this case Splash has a really hard time turning the black pigment to an all white pattern, but that is not to say the Splash mutation cant be used on a similar fashion as Dominant white would but on different backgrounds beside self black(Extended black E/E, Ml/Ml).

Splash can be used on eb/eb, e+/e+, eWh/eWh wild pattern to produce a Red Pyle type bird or with Columbian and the Pattern gene to produced Red White Laced patterns.

I will list a few breeds that have Splash as eumelanin diluter(black feathers) while preserving their rich gold/red color

Red Shouldered Yokohama

Splash Swedish Flowery Hen

Splash Laced Red Wyandotte



Basically, I was responding to the poster that said it was a shame that Dominant white diluted the shanks too much because there was a few patterns he would like to have with dominant white, so I assumed that a self white bird was not being referenced by the poster, in this case Spalsh can work as dominant white substitute(if bred for of course as not to breed the birds with too many dark patches), Splash also does not seem to dilute the shanks nor the gold/red color like dominant white does.

This means that white d'Anvers are dominant white. The other varieties have slate shanks while the whites have white shanks. I have what is probably a blue lavender hen with very dark shanks. It is interesting how neither dilution lightens the shank coloration, however, she looks almost white. I know she is blue lavender because of experimental breeding. Her lavender son, as produced with a porcelain, is much darker and only produces black and lavender chicks when crossed with his half sisters though she has produced blue.

Neither Blue or Lavender inhibit shank pigmentation. Or perhaps I am missing something on your post?

Nope. Just poorly written on my part. I was sharing that lavender and blue do not inhibit shank coloration, therefore being what coloration the hen had, and thought it was very interesting.

I agree, I would like to point out that the White found on Araucanas are also Dominant White, it has such strong effect on the birds that they had to change the standard to reflect yellow shanks, I dont believe that the Ameraucana breed standard will ever allow white shanks on their birds to include Barring/cuckoo patterns.

One can also Work with Dun to produce a light colored pattern on extended black without diluting the shanks, even if Dun is a mutation of the dominant white gene

I see what you are trying to say .
the Splash when used as eumelanin diluter preserve the richness of the gold but does not give a complete red pyle pattern .where only the black feathers are replaced by white feathers .but the body pattern stay intact .
I found out adding the Mahogany to the dominant white will keep the golden colour rich, the delution is not apparent .

love the splash laced red wyandotte pattern .I think is stunning .
