Hello BYC Forum Family,
I am writing this post to reinforce the correct gene/mutation nomenclature in chickens.
Lets start with the fact that chickens like all birds, some reptiles and some insects follow the ZZ and ZW sex determination system.
Dominant, incompletely dominant and codominant genes are Capitalized, recessive genes start with lower case, wildtype genes end with a + sign. The forward slash is to separate the allelic mutations and the comma sign is to separate non allelic mutations.
For example female red jungle fowl are e+/e+, b+/- and female barred rocks are E/E, B/-
Since there can be multiple allelic mutations on a single allele, the caret ^ sign is used when the researchers have given them names, for example: on the recessive white allele C+ is the wildtype none white gene, the recessive white is c and c^al is recessive albinism, another example is the dominant White allele where i+ is non white, I is dominant White and I^d is Dunn
