She is not a standard recognized variety, but is a true breeding variety nonetheless. She is the gold version of our standard-recognized Silvers. Depending on the male version of her color she could be a \"black breasted red\" or a \"light brown.\" BBRed males have clear hackles, while light brown males have hackle striping, as do our silvers. Not a bad looking specimen. If you acquired a good silver male and crossed it with her, all the pullets would be pure silvers, all the males would be mixed (impure). That is because the dominant S gene(silvers) and its\' counterpart (allele) small s are carried on the sex link chromosome. In birds, males get the extra gene-carrying chromosome, and that is why males can be mixed while females must be pure for all sex linked traits. Another example would be the gene that produces dermal melanin, another the type of barring found in Plymouth Rocks.
