Anthracite budgerigar mutation the strain and continues to report on its development. Initially found only in Germany, by the end of 2008 descendents of this original mutation had been exported to America, Belgium, Canada, England, Finland, Holland, Italy, Norway, Sweden, Switzerland and Pakistan. The Anthracite mutation has an incompletely dominant relationship with its wild-type allele. That is, it shows a visible effect when present as a single factor (heterozygote or SF) and a different effect when present as a double factor (homozygote or DF). In the green series varieties the SF Anthracite Light Green has one Anthracite allele and one wild-type allele at
