A decisive impulse to the
breeding in captivity of the Goldfinch, but in a generalized manner of all the
has been given from the advent of the color mutations, ereditablesi genetic anomalies that
transform the phenotype of the subject changedregarding its ancestral shape.
The today sure fixed mutations on the Goldfinch are:
Tawny, recessive mutation sex-tied, characterized from the
transformation of the black eumelanina in
tawny. The effect that ne derives is that the zones previously interested from the blackone become of tawny
tonality, and the zones
interested from feotransform in a brown much warmth.
Mutation Agate , recessiva sex-tied, characterized from one
partial reduction of the black eumelanina and from one nearly total passing of the tawny
feomelanina. The contrast between the black one nearly unchanged of the wings and the
tail, and the back(gray-silver) and the chest (nearly completely white man), confers to
such subjects a truly entusiasmante aspect.

Mutation Isabella , sex-tied recessive, gushes from the Agate
crossing for Tawny, from which the formation of ancestral genotype double
(passepartout), able subjects of giving to feminine descendancys Agate, Tawny and, for
Fenotype is introduced like a Tawny one diluted.
Mutation Pastel , sex-tied, characterized recessive from
reduction of the eumelanina and the feomelanina, with final fenotype result of a general
color pastel of the colors of the cape.
Satinč mutation , tied recessiva sex, are without doubt the
beautifulst today fixed mutation in the Goldfinch. The passing of the feomelanina and
nearly the total reduction of the eumelanina confer to the Goldfinch a truly spectacular
livery, with the design as soon as pointed out from beige a much slender that is
detached clearly from red of the template and the yellow of the crossing the
Yellow, autosomale mutation dominant, from me officially fixed in 1997 and
described on Ornithological Italy ofJanuary 1999,
characterized from one macrocoscop icinfiltration of yellow on all the cape of the
subject. It is the onlymutation that instead diluting, adds lipocrome where lipocrome
The more valuable subjects have the design with littles lobbers and the lipocrome yellow
more candid possible.
A lot interesting would have to be the final aspect deriving from the
summary one of the
Yellow mutation with the sex-lied mutations, above all Agata and Satinč.
Other not common mutations but in phase of sure stabilization are the Opal
and the Albino , both recessive autosomale.
Other ulterior mutation, fixed from those fucine of genetics that are
the Dutch breedings Belgian and, is the
Witkop mutation, (Head white
woman Yellow Shoulder) characterized from the disappearance of the
black cross on the head and from sottopiuma the white man The
mechanism of hereditary transmission is of the type Autosomico
