FAQ: Combinations of alleles of the same gene

FAQ: Combinations of alleles of the same gene are indicated by writing the mutant names one after the other, for example PastelIno. A capital is used to indicate the start of each mutants name.

But how do we write the name of a combination with epistatic genes?

Well here we have an  easy answer: exactly the same as we write alleles of the same gene! The mutant (gene) names one after the other. Why? It are also two (different) alleles that are creating a (non wild type) phenotype.

    Must say I thought that epistatic genes were not alleles? I thought alleles were alternative genetic mutations for the same locus.

  2. In DNA we have some parts that are coded for amino acids. That part of that DNA is a what we call a gene.If a mutation (a change in the DNA code) appears in a gene, we talk about an allele (a changed gene).
    We can have several alleles of one particular gene, different codes from one allele. Pastel and NSL ino are alleles from the same a-locus (same gene, some locus – same place in DNA). If we have an epistatic gene, that means that we have a mutation in a particular gene that can influence another, completely different, mutation, somewhere in the DNA of that bird (not same locus). So here we also have two different alleles (from different genes – loci) that create a phenotype that is different from the wild type
