All our chickens have alleles of the "E-locus" aswell in gold as Silver phenotypes.
They can be transformed to different phenotypes by "transforming" genes.
4 groups of transforming types: diluters, patterners, changers and reinforcers.
Everything started with the "Bankiva" colouration.
(all genes are present with there original alleles, marked with a "+").
Simpely said a total mix of "red/black" (the only 2 existing colour pigments).
For now we know 4 important mutations of the e+ allele (alleles without that "+").
Those mutant alleles of the original e+ allel are E, ER, EWh, eb.
(3 less important mutations are: es = speckled and ebc = buttercup and ey = wheaten recessiv).
They can be homozygous (pure E/E, ER/ER, EWh/EWh, eb/eb) or heterozygous (unpure E/ER, E/EWh, E/Eb, E/e+, ER/EWh, ER/eb, ER/e+, EWh/eb, EWh/e+, eb/e+).
(with a Capital normaly dominant over those without a capital who are recessive).
Those 4 different basic phenotypes and the original are always golden or silver.
The chickens can have the s+ (gold) or S (silver) or both alleles (only if a cock)
Because this is a sex-linked gene the hens are s+/- (pure gold) or S/- (pure Silver).
(hens are hemizygous for the S gene because they have only one allele of it).
Cocks can be s+/s+ (pure gold), S/s+ (unpure Silver) or S/S (pure Silver).(cocks are homozygous {2 identical alleles} or heterozygous {2 NOT identical alleles}).
There are also other ("transforming") genes and different genes combinations.
Those can transform the original phenotype (that of the bankiva and is 4 mutants) into other phenotypes.
(also here Dominant and recessive alleles, also those genes can be homozygous, heterozygous or hemizygous {for the sex-linked genes}).
These basic based genes can be diluted by: Bl, lav, Di, ig, Cb.
These basic based genes can be patterned by: B, mo, Pg, Db, Co.
These basic based genes can be changed by: I-Id-Is, choc, c, mz, cha.
All of them can also be reinforced by: Mh, Ml.
