General information
The classic grey phenotype in alpacas is a dilution factor that brightens the coat’s base colour. The phenotype is usually the result of a combination of black and white or fawn fibers in the coat, which gives rise to the grey appearance. A dominant mutation in the KIT gene was identified as the causative genetic variant for classic gray. All classic grey alpacas were observed to be heterozygous.
Clinical features
Animals with this phenotype are characterized by a coat colour that ranges from dark silver or charcoal grey to lighter shades of grey. The grey coloration can be evenly distributed throughout the entire body or may exhibit patterns such as roaning or spotting.
Additional information
No animals homozygous for the classic grey mutation were found, which suggests that the mutation is most likely embryonic lethal in the homozygous state.
