I work with Silkies and Different crosses with Ameraucana.
White and Black definitely get me the color combos I described plus several others.
A Wheaten Ameraucana crossed with a Crele Golden Phoenix got me solid black chicks. they are black sexlinks. Please tell me the genetic possibility of that.
I have Barred Silkies that no barred bird was ever part of the breeding plan. I just picked females with spotted patterns on their wing feathers until I now have a cage full of Barred Silkies. Wings, Tails and body feathers are barred. Now I plan to breed back to Perfect TYPE silkies until I have nice beards and topknots with a full barred pattern.
Recessive lavender has been associated with poor feather quality and even lack of feathers in some breeds. Lavender dilutes both black and red; changes black to grey and red to cream. Blue fowls termed "self blue" are normally lavender homozygotes. A mating of two lav homozygotes (blue fowls) will produce blue offspring. Lavender causes dilution by inhibiting the transfer of pigment granules from melanocytes, which produce them, to the feather structure. Lavender expression in homozygotes is present in chicks and adults.
Dominant White is Incompletely dominant. Influences eye pigment. Inhibits black pigment, eumalanin. This gene is ‘leaky’ and will allow black specks through. Generally not as efficient at producing a solid white bird as are two copies of recessive white. Heterozygotes of dominant white, I/i+ are often grey with the grey color visible in the chick down. Dominant white dilutes, but does not eliminate, epidermal melanin. I have bred White Leghorns to Black Ameraucanas and gotten Blue and white with black Splashed Chicks. Blue with Black Splashed chicks and white with blue splashed chicks. Same results with Silkies. I also have Blue splashed with chocolate silkies, Lavender splashed with Chocolate Silkies, Isabel splashed with black silkies, and as many as 6 colors on one silkie rooster. You are correct about many possibilities associated with white genes. But do not discount those possibilities of White genes to get both blue and splash from black x white birds. It is more accurate to research horse color genetics. My Silkies with the mottled gene are more like Arabians that are born solid black and if they have white eyelashes, you can count on the foal to be white by the time it is 10 years old. My Blue silkies start out as partridge chicks turn blue with their adult feather molt, then become chocolate that fall. The Paint gene in Silkies is most closely related to the Appaloosa genes of horses. If I have a Black or white chick hatch out with pink toes, I know the offspring of 2 white parents will be splash and the offspring of two black parents will be splash OR Pinto. OR Paint. I have White with Cream Splash and White with Gold Splash and White with Chocolate splashes and Gold with red splash Silkies. But they are not hatched that way, they grow into those colors.
The smoky gene is an allele belonging to the dominant white locus. Smoky is dominant to dominant white in both chick down and adult plumage in that extended black with I/IS (E/E I/IS)results in grey chick down and adult plumage. Research to date indicates that i+/IS heterozygotes express more the wild-type phenotype with respect to this gene indicating a recessive character with respect to the wild-type. Smoky is dominant on the chick down of IS/i+ heterozygotes in that down that should be black is grey. The melanosomes resulting from the expression of smoky resemble those resulting from Andalusian Blue. Smoky dilutes black much more than red/gold. An important difference between Smoky and Andalusian Blue is that Smoky in the homozygote state produces a grey/blue bird while Andalusian Blue homozygotes are splash. Therefore, Smoky fowl will breed true.
BLUE is Incompletely dominant. Andalusian blue-dilutes black: blue pigment is a modified black. Two nigrum genes, E, and one Bl gives a blue chicken; two Bl genes gives splash.
Recessive White Gene Thought to give a cleaner white than dominant white. Varieties of White Plymouth Rock, Wyandotte, Minorca, Orpington, Jersey Giant, Dorking, Langshan, Silky and others often carry recessive white genes. Many varieties carry both dominant and recessive white. Allows dark eyes. Pigmentation in chick down varies.
The order of dominance among the recessive white alleles is: C+>c>cre>ca. The presence of other pigment inhibiting or enhancing genes will influence the chick down color. Some adults have a grey/blue color.
So a white and black original great grand parent cross will affect the dilution of blue
Blue is not an original color from the Indian Red Jungle Fowl.
Blue is a man- made color. There had to be a start somewhere in history. BLUExBLUE now gets BLUE.
But it took many generations to lock that in.
You can still get blue by mixing Black and White
My Arabian Mare has the silver gene which in chickens is the lavender gene.
If I breed her to a black stud, I have a 50% chance of a Silver or a Black, but her black offspring can be bred back to a silver and get silver.
If I breed her to a silver, I get a silver every time.
I am breeding her to a bay, which is the equivalent of a red rooster with a black tail and wings.
So, What will I get?
The Paint Mustang is really equivilant to the mottled chicken gene. All the different colors of horses that escaped from settling the west bred un hampered by humans. And the Painted Mustang is every color imaginable. The Appaloosa is the extreme expression of the Spanish Barb flea bitten gray. I have had a few Flea Bitten Gray Arabians. They come in red, black, gray, brown, or gold dots on a white background.BUT, they start out as those colors solid, and lighten as they age..http://www.whitehorseproductions.com/ecg_basics3.html
