    Question for the graduates in (whatever) biological sciences


    When this are the E-locus alleles with their corresponding (mutated) amino acids on the different positions on MC1R producing the different plumage color populations "il disegno/colore primario" :


    E/E (Australorp) - Glu92Lys, Met71Thr // Glu92Lys, Met71Thr => 2 mutations
    ER/ER (Livorno) - Glu92Lys // Glu92Lys => 1 mutation equal with E/E (Australorp)
    ER/ER (Fayoumi) - Leu133Gln // Leu133Gln => 1 mutation
    eWh/eWh (wheaten) - Thr143Ala // Thr143Ala => 1 mutation
    eb/eb (brown) - Glu92Lys, Met71Thr, His215Pro // Glu92Lys, Met71Thr, His215Pro => 3 mutations 2 eqaul with E/E (Australorp)
    e+/e+ (wild-type) - Met71Met, Glu92Glu, Leu133Leu, Thr143Thr, His215His // Met71Met, Glu92Glu, Leu133Leu, Thr143Thr, His215His => no mutations

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

    Leu133Gln, Thr143Ala // Leu133Gln, His215His => 2 different mutations on each allel, 1 ER (Fayoumi) amino acid with 1 eWh (wheaten) amino acid // 1 ER (Fayoumi) amino acid with 1 eb (brown) amino acid

    In the last amino acid combination I wrote an error, must be this :
    Leu133Gln, Thr143Ala // Leu133Gln, His215Pro => 2 different mutations on each allel, 1 ER (Fayoumi) amino acid with 1 eWh (wheaten) amino acid // 1 ER (Fayoumi) amino acid with 1 eb (brown) amino acid

    Una cosa, non esiste "aminoacido ER", "aminoacido eWh"... eccetera, sono diverse sequenze aminoacidiche, corrispondenti a diversi alleli. Ad esempio nel caso dell'allele E, la differenza, rispetto all'allele originale e+, è che l'aminoacido metionina in posizione 72 si è trasformata (per cambio di una base) in treonina e l'aminoacido glutammina in posizione 92 in lisina. Così via per gli altri alleli...
    Per l'allele e+ ti sei dimenticato dell'aminoacido cisteina in posizione 213.

    I not said "aminoacido ER", "aminoacido eWh"... eccetera but I wrote ... "corresponding" ... , the question was not how they transform but what phenotype correspond to the last "strange" mutation combination !

    * Was let out variations Arg213Cys because this mutation on position 213 probably has no/little effect on phenotype !

    I reacted on this your phrase:
    "... 1 ER (Fayoumi) amino acid with 1 eWh (wheaten) amino acid // 1 ER (Fayoumi) amino acid with 1 eb (brown) amino acid"
    (I think they took as original also Cys in position 213, otherwase, they had to indicate in all mutations also the mutation Arg/Cys.)

    ... 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...

    1. About the mutation on position 213 probably having no/little effect on phenotype was given me first-handed by a person who was co-worker on the elucidation of MC1R.

    2. That was exactely why my question was made here to professional(s) (see the subtitle) to give an answer that could help us simple breeders.

    I rephrase for you than :-)

    Leu133Gln, Thr143Ala // Leu133Gln, His215Pro => 2 different mutations on each allel : 1 ER (Fayoumi) "amino acid : Leu133Gln" with 1 eWh (wheaten) "amino acid : Thr143Ala" // 1 ER (Fayoumi) "amino acid : Leu133Gln" with 1 eb (brown) "amino acid : His215Pro"

    PS I can't think of a better cartelle than the one of "GENETICA DEI COLORI" to post my question in, you not agree ?

    Hoping for a clarifying answer :-)

    But this: "Leu133Gln" isn't an aminoacid...... Aminoacids are leucine, glutamine and so on.
    I did not understand your question.

    This: "Met71Met, Glu92Glu, Leu133Leu, Thr143Thr, His215His" does mean nothing. If they are no mutations, Thr143Thr (and so on) (nothing changed in position 143) is not correct to write, threonine has remained threonine.

    When the amiono acid "leucine" who is at position 133 on the MC1R mutated to "glutamine" it is written shortened as "Leu133Gln", even more shorten is to write it as "K133Q" since the amino acid abbreviations for leucine is "K" and for glutamine is "Q"

    Special for you (but also for the others who follow this post) I wrote it, in a kind of a table, for e+ along with the others :

    Allele...71....92.....133....143....213....215 <=(positions)
    e+.......Met...Glu....Leu....Thr....Arg....His <=(no mutants)
    ER........–....Lys.....–......–......–......– <= (1 mutant)
    E........Thr...Lys.....–......–.....Cys.....- <=(3 mutants)
    eb.......Thr...Lys.....–......–.....Cys....Pro <=(4 mutants)
    ER-fay....–.....–.....Gln.....–......–......– <= (1 mutant)
    ewh/ey....–.....–......–.....Ala.....–......– <= (1 mutant)


    But I see it not keep in position !!

    Non è questione di "come la voglio io" o meno, è questione che sono state scritte delle cose completamente errate. Come ho detto, non esiste aminoacido ER e non esiste aminoacido His215Pro. Esiste l'allele ER con una determinata sequenza aminoacidica ed esiste la mutazione His215Pro, che vuol dire che nella sequenza aminoacidica dell'allele ER, in posizione 215 si trova l'aminoacido prolina. Danny, tu hai studiato molto la genetica e hai imparato tante cose e ok ed è molto positivo, da apprezzare ecc. Quello che invece mi da fastidio è quando qualcuno, che non ha studiato biologia, medicina o materie affini, vede scritte certe cose e senza capirle le riporta. La tabella che dici di aver scritto tu per me, la conosco già e non è una tabella fatta da te ma copiata da un sito. Se so cosa è un aminoacido, se so come è fatto il DNA, i geni, se so cosa sono le mutazioni, sicuramente non dico mai che His215Pro è un aminoacido.
    Per quanto riguarda la tua domanda, non ho capito a che sequenza ti riferisci, non ho visto nessuna sequenza.

    Indeed what I wrote I not "invented" myself but it comes from publications.
    About the way of writing, see posts #12 and #13.
    When these matters discussed with others was not a problem to understand what was talked about.
    What concern my question, if it takes 17 posts to formulate an answer what phenotype would be the allel combination "Leu133Gln, Thr143Ala // Leu133Gln, His215His" I suppose you not know the answer !
    You could just told so or asked what it could be but let's forget it and stop this filibuster debate.
    Grazie

    Publications not write "aminoacid: His214Pro"........
    You must write a sequence, alone this mutations say nothing. But I immagine you are meaning (refering on the E locus) a chicken with genotype ER/ewh and an other with genotype ER/e+. The question is not right but I think I understood you. You know which phenotype have an ER/e+ chickens or an ER/ewh chickens, better of me, so if was this your question, I not understand why you did it.

    :-) Tunde you not read what is written, I not spook of genotype ER/eWh nor of ER/e+ , what I spook of was are 2 different amino acid mutations on each allel :
    Leu133Gln, Thr143Ala // Leu133Gln, His215Pro
    and this is reality not scienfiction !

    This was also the reason why I asked the help of someone graduated in biological sciences and not of a regular breeder.

    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.)

    Is nothing strange on 1allele with more than 1 mutations of his amino acids, look :
    eb/eb (brown) - Glu92 to Lys, Met71 to Thr, His215 to Pro // Glu92 to Lys, Met71 to Thr, His215 to Pro => 3 mutations 2 eqaul with E/E (Australorp)

    * I wrote a little more clear and understandable for everybody , ex. His215 to Pro ;-)

    Sapevo già la differenza tra le 2 sequenze, ciò che stavo dicendo è che per forza hanno preso come allele originale quello con la cisteina, in posizione 213 perchè se avessero preso come originale la sequenza con arginina, nella stessa posizione, per tutte le mutazioni (E, ER, ewh and so on) avrebbero dovuto indicare in più la mutazione avvenuta in questa posizione, visto che tutti gli altri alleli (in posizione 213) hanno una sequenza di basi che codifica per la cisteina...
