The distinctive color is caused by the action of an autosomal recessive gene, commonly designated as "''lav''", which reduces the expression of eumelanin and phaeomelanin so that black areas of the plumage appear pale grey instead, and red areas appear a pale buff.Crawford, Roy ''Poultry Breeding and Genetics'', Elsevier, 1990 Description The "lavender" gene (''lav'') in the chicken causes the dilution of both black (eumelanin) and red/brown (phaeomelanin) pigments, so according to color background, dilution due to "lavender" gives a sort of plumage color patterns: On an extended black background, this condition causes the entire surface of the body an even shade of light slaty blue, which is the typical phenotype known as '"self-blue"'. On a red/brown color plumage background, lavender gene degrades colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
