JORGE, W e CUNHA, LM. Inheritance of a new albino mutation in Brazilian free-range black chickens. Rev. Bras. Cienc. Avic. [online]. 2008, vol.10, n.3, pp. 153-156. ISSN 1806-9061. http://dx.doi.org/10.1590/S1516-635X2008000300003.
A genetically recessive albino mutation, which inhibits pigment development in the eyes, skin, and feathers of domestic chickens from Brazil, is described. This mutation appeared in a flock of completely black chickens of a private breeder. There are no information on the origin, breed, or specific line of the birds. Pigment inhibition is apparently complete in the feathers and eyes. Bird sight is very impaired, but no histological examination was carried out. Ratios obtained in F2 and backcrossed birds indicate that a single autosomal recessive gene is responsible for the condition. The data suggest that the absence of melanin in the eyes, skin, and feathers (symbol cc) is a mutation of the pigmented C wild gene.
