    Here are some mutations for Genetics folks........

    EXTENDED BROWN, E
    Inherit: Autosomal Incomplete dominant
    Linkage: Unknown
    Characteristic: "this mutant color gene extends the distribution of black and dark brown pigment throughout the plumage. Both sexes appear the same"
    Reference: Journal of Heredity, 1978
    Source: British Range. English White, and Tuxedo

    RECESSIVE WHITE, wh
    Inherit: Autosomal resessive
    Linkage: Unknown
    Characteristic: "This mutant color gene produces a white bird with dark eyes when homozygous and a two-color pattern known as "tuxedo" when heterozygous. The "tuxedo" pattern is white on the ventral surface including the neck and face while the dorsal surface is an intermingling of black and brown pigment."
    Reference: Journal of Heredity, 1978
    Source: English White, Tuxedo, British Range (since British Range can be in tuxedo forms)

    YELLOW, Y
    Inherit: Autosomal Dominant
    Linkage: Unknown
    Characteristic: "This mutant color gene results in the appearance of a rich, golden-wheat- straw colored bird. The general pigment distribution is the same as in the "wild-type" Japanese Quail except that the wheat-straw shafting of the back and hackle feathers is much wider and the wing bow and head feathers are also wheat straw yellow colored."
    Reference: Japanese Journal of Zootechnical Science, 38: 163-166, 1967
    Source: Manchurian Golden

    DILUTE, al^D
    Inherit: Sex-linked recessive; al^D, al
    Linkage: Sex Chromosome
    Characteristic: "This mutant pigmentation gene causes an overall reduction in pigmentation. The shanks are free of pigment, down is light in color as is the adult plumage. Eye color is NOT affected. It is also one of the alleles at the A1^+ locus."
    Reference: Poultry science, 53:1908, 1974.
    Source: Fawn/Cinnamon

    IMPERFECT ALBINISM, a1
    Inherit: Sex-linked recessive; al^D, al
    Linkage: Sex Chromosome
    Characteristic: " This pigmentation mutant results in subnormal levels of pigmentation of the eyes and feathers of affected birds. Faint stripes on the backs of the adults is apparently due to structural color only. Viability is reduced both before and after hatching in birds homozygous for this gene."
    Reference: Journal of Heredity, 57: 119-124, 1966

    RED HEAD
    Inherit: Autosomal Recessive
    Linkage: Unknown
    Characteristic: "The underfluff of both sexes is smoky black, the base of the feathers are white with irregular bands of black and rust. Feathers are usually tipped in rust. The beak and shanks tend to be whitish color and eye color is unaffected. Females are generally lighter in color with the dorsal being darker. Breast is whitish with upper breast feathers tipped black and rust. Flanks and abdomen are white. Head is white with a black cap whose feathers are tipped with rust. Males are much darker overall. There is considerably more black in all feathers with darker rust tips. Breast tends to be light rust carried well down to the abdomen. Head is dark rust with a black cap or head streak.

    RED
    Inherit: Working on it [​IMG] Definitely not sex-linked
    Linkage: Definitely not sex chromosome
    Characteristic: Working on it
    Reference: Unpublished
    Source: Red Golden/Scarlett, Roux Dilute, Red Range

    WHITE BEARD, bd^w
    Inherit: Autosomal recessive
    Linkage: Unknown
    Characteristic: "On brown feathered birds this trait appears as a small white beard-like patch of feathers under the lower beak in the interramal tract."
    Reference: Canadian Journal of Genetics and Cytology, 1978
    Source: Pharaoh (wild-type), Jumbo Brown varieties

    WHITE-BREASTED, wb
    Inherit: Autosomal recessive
    Linkage: Unknown
    Characteristic: "The dorsal plumage is similar to the wild-type pattern. White feathers cover the face to just above the eyes. the underside of the neck, the entire breast, and the sternum up to and including the vent area. The primary feathers down to most of the secondary feathers as well as their coverts are also white.
    Reference: Canadian Journal of Genetics and Cytology, 1978

    WHITE-CRESCENT, cr
    Inherit: Autosomal recessive
    Linkage: Unknown
    Characteristic: "A crescent-shaped band of white feathers extends across the breast of the brown feathered birds. This band is located at the junction of the ventral cervical and the pectoral tracts."
    Reference: Canadian Journal of Genetics and Cytology, 1978

    WHITE PRIMARIES
    inherit: Autosomal recessive
    Linkage: Unknown
    Characteristic: Primary feathers are white on an other-wise colored bird.
    Reference: Unpublished
    Source: Pharaohs (wild-type)--> Shelleyd is exhibiting this in her stock

    FAWN, Y^F
    Inherit: Fawn (F) incompletely dominant to y+ and codominant to to yellow (homozygotes not lethal)
    Source: Manchurian, Italian

    BLEU, bl
    Inherit: Recessive
    Characteristic: This recessive mutation replaces the brown color of the wild-type with bluish grey an the cream-colored markings with white.
    Reference: Perramon, 1988

    RECESSIVE SILVER, rs
    Inherit: Autosomal Recessive
    Characteristic: Egg Production of homozygote females is affected. Need to pair up Homozygote males and heterozygous females to reproduce normally.
    Reference: Watanabe an Homma (1982)

    I have had one of these as well, though she escaped on me last fall [​IMG] (ETA: hatched from my birds)

    Maybe the bird thought she was in for experimentation and freaked? [​IMG]

    I bet you will get another one [​IMG]

    Idk, that was a year ago when I still had mine separated, and I haven't seen one since. I lost a lot of my browns over the winter, my luck whichever one(s) contributed to that were ones that got ate [​IMG]

    White Primaries are also in some of my Jumbo Browns. Now I have more Whites to study, thank you.

    You are going to edit this 1st post and add some of the others as time allows I am sure?
    Like the Silver.

    Ok, got question for you on the Extended Brown. Could you explain the difference between this and the British range? Or do you by chance have a pic of one of these birds? I am trying to understand the difference between the Extended and the British. Thanks.

    The British Range contains the color gene "extended brown." It isn't the name of the variety, just the gene that determined it which is E

    Does that make sense? I am trying to keep it simple [​IMG]

    Edited to add: Your photo is an excellent example of the Dark British Range Variety [​IMG] Beautiful photograph [​IMG]

    British Range is the result of the presence of extended brown, the wild-type (which is the pharaoh variety), and red head genes to be exact [​IMG] That is why there are more shades in the plumage [​IMG]
