Description |
|
The gene for silver is another gene causing a lightening of the basic colour. The silver-gene has no impact on pheomelanin like the genes for cream and champagne and only leads to brightening of black coloured areas. Especially black coloured hair of mane and tail appears brighter because of the occurrence of white and grey hairs. The gene for silver is inherited autosomal-dominant and one copy of the gene is sufficient for the phenotype.
The silver dilution is also known to be associated with an inherited ocular syndrome known as Multiple Congenital Ocular Anomalies (MCOA).
