Some photo and some consideration of selection and
genetics on the reproductive season as soon as passed, the reproducers and changed and
ancestral, obtained novels, in my breeding.
The reproducers were constitu ted from a sure number of ancestral
subjects, of the
Subspecies Carduelis c. tschusii (variety is of plain that of mountain) and the
Subspecies Carduelis c. major (of which, finally, they are successful to obtain
the reproduction in a common gabion from 90 cm), some braces of Pastel, Agate, Satinč and
Yellow. In particular, the nominal Species (Carduelis carduelis c.) and
the ancestral Subspecies ( Carduelis c. maior and Carduelsi c. tschusii, these
last ones represented in the same photogram), are not never between of like a half-breed
they, that with the obvious attempt of preservare the purity is of the nominal shape that
of the Subspecies, avoiding the obtaining of intermediate mestizos and therefore of
insufficient value is aesthetic that selective.
All varying changed of the Goldfinch do not come, in my breeding, selected in direction of
the Subspecies maior whose reduced it loads the feomelanica exalts some
mutations, like the Agate, but of it it penalizes others, like the Tawny
one.
Subspecies maior beyond that in the Agate, it is also to prefer in the selection
of the mutation Pastel, whose fenotipico effect of " appastellamento " of the
melanine is exalted when in such mutation takes part subject of adequate ransom.

Of all the opposite one the Yellow mutation appears the inherent
speech,
where the remarkable size and above all the reduced one loads feomelanica with the
Subspecies Carduelis c. maior it stretches to dilute the lipocromo excessive
yellow, with unpleasant and muddling final effect fenotipico decidedly. Based on my
selective, better experiences it turns out to you fenotipici obtain when in the Yellow
mutation they take part subject of medium or small ransom.
On the le ft Goldfinch male in
Yellow mutation, of medium ransom with good and pleasant
fenotipiche characteristics, which lipocromo yellow homogenous, clean template and very
delimited.
To right obtained Yellow Goldfinch after selection towards the Subspecies
maior with the attempt to increase the ransom of the changed
subjects. To forehead of a ransom increase, he is but obvious also a lipocromo yellow
polluting, not clean template and decidedly unpleasant final fenotipico
result.

Finally, some word on the fascinating Satinč mutation: from the connection between
male bearer of Satinč for female Agate, I have obtained some male (50 % of the
males)
Agate bearer of Satinč, assisting therefore in my small breeding to the important
phenomenon of the multiple Allelomorphie (verification when determining " locus "
chromosomic it can be occupied from two or more Alleli various). The males Agate bearers
of Satinč reveal a phenotype Agate for the dominanza of the gene of the Agate (gene of
the " dilution") on the gene for the Satinč. Such phenotype Agate is but
ulteriorly reduced regarding the classic phenotype of the Agate in how much the gene of
the Agate reveals " a partial " dominance on that one for the
Satinč, which the design of the Agate equally succeeds to softly express an effect on the
phenotype reducing further on.
In the photo, Goldfinch male Agate bearer of Satinč phenotype
appears Agate for the dominanza of such gene on the allelico gene for the Satinč. Such
phenotype, but, appears ulteriorly reduced respect to an Agate classic, above all in the
feomelaniche zones. The eye, to the birth, appears red until the fifth sixth day of life.
To dumb aim, I promise my self to insert new such photos of splendid
subjects.
