    how does autosomal barring affect roosters? are there other autosomal barring genes?

    what's the difference(genetic) between these roosters?

    why some autosomal barred rooster look like black tail white but the hens don't?

    They both are the same. Only the first one is Hen Feathered. Genetically they both are ER Db Pg

    Quote:The second picture is an example of how auto-barring is supposed to look. The top picture is a hen-feathered cock (campine), hen-feathering doesn't let them have sexual dimorphism among the pattern colors.

    Autosomal Barring make up a combo of genes. Db(darkbrown) Ml(Melanotic) and Pg(Pattern Gene), the expression of theis phenotype(looks) can be altered if based in different "e" alleles.

    Males based on eb/eb are Black tail white, but hens remain autosomal barred..
    if based on ER/ER roosters and hens are both autosomal barred.


    what's the difference between the two boys you showed? the first one seems to be based on eb/eb, but has HenFeathering(making it look like a autosomal barred hen). the second rooster is based on ER/ER therefore looking autosomal barred..

    The top bird is lacking male Saddle Feathers also has shorter Hackle and Sickle Feathers than the breed should so there is a good possibility that there is some Hen Feathering (Hf) in play.
