    Ah, ok, ho chiuso la tabella, mi ricordavo male, allora hanno preso, come originale, entrambe le sequenze.




    Yes, that was what I wanted to let see. I agree this are the very little details but is this what make the differences in the phenotypes.
    Is what you made me interested in ... so thanks for that ;-)

    (Non mi metto sicuramente a memorizzare delle tabelle con aminoacidi...)




    The most important locus is the E-locus. When we want to understand better his different phenotypes "il disegno/colore primario", we MUST know/learn all about these little nothings called amino acids because they are responsible for every change of each phenotype.

    In other words, to can understand/explain a coloration we can't do it only with words and hobbynames alone but we must know the complete genotype is responsible for everything "il disegno/colore primario" & "il disegno/colore secondario", they go hand in hand ;-)

    What plumage color disegno/colore primario will produce this sequenced allel combination proven also to excist ?

    Leu133 to Gln, Thr143 to Ala // Leu133 to Gln, His215 to Pro => 2 different mutations on each allel




    Well I show you a chick :

    ... però se non spieghi dalle basi ciò che scrivi, sinceramente non so cosa se ne fa un allevatore che non sia un medico, veterinario, biologo ecc... Intendo, secondo te questa discussione la può trovare interessante chi non sa di che cosa si parli? Se vuoi discutere sull'argomento, secondo me dovresti spiegare come è fatto il DNA, cosa sono esattamente i geni...




    "modificando geni che trasformano la coda nera in una coda con penne colorate"

    Does this ring a bell ?

    Danny, if you are asking seriously what phenotyoe is this and you are refering on 1 chicken with 1 allele with 2 mutations and with the other allele with other 2 mutations, this phenotype not exist because the mutation Leu133Gln and Thr143Ala together, on the E locus not exis, for now it's no allele like this as it's no for now allele with the other 2 mutations. Or maybe exist but we know nothing about, for now. (Or an other possibility, I not readed about this new mutation.)

    It is of a recent occurrence the DNA sequencing of 3 Birchen alleles, as once previously thought of as only 1 allele - ER Birchen.

    Three different alleles of the melanocortin 1 receptor locus (MC1-R) :
    -ER (Livorno) Glu92 => Lys
    -ER (Fayoumi) Leu133 => Gln
    -ER ("Funky") has the dominant wheaten mutation Thr143 => Ala and the Fayoumi birchen mutation Leu133 => Gln combined.


    Cosi, certe cose misterioso non sono più un mistero !

    I talked about the 5 alleles of the E-locus which are responsible for the "disegno/colore primario" of the basic 5 phenotypes of EACH chicken.
    That is how we can determine the 5 basic disegno/colore "families" !

    1 of these 5, the "ER" (Betulla) was found to exist in 3 variants (mutations) because of 3 different amino acids (the building blocks within each allel).

    All 3 variants occur in the typical Italian varieties, that is why I found it interesting enough to tell you about this, so you can better understand what is going on in your hobby.
