Flash on the season of breeding 2000

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 constituSei Nidiacei di Cardellino a poche ore dalla schiusated 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.Cinque robusti novelli di Cardellino a otto giorni di vita 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.mutazione Giallo

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.

Novello agata portatore di SatinčIn 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.
