    Question about color. I have a white pullet, yes she has laid eggs so I know its a she, with light buff around the underside of her beard like a necklace..
    I thought hens couldn't only have 1 color gene. I'm confused!

    Hens have only 1 allel of the sex-linked genes. Recessive white "c/c" or Dominant white "I/I" aren't sex-linked genes.

    There are 2 kind of color-genes, sex-linked and autosomal color-genes.
    In birds (as chickens are) males have 2 alleles of a sex-linked gene => S/S , females have only 1 allel of it => S/- (S stands for Silver).
    Of autosomale genes males and females have 2 alleles of it => c/c (c stands for colorless = recessive white) => I/I (I stands for Inhibitor = Dominant white).

    Marquisella said she was confused because she thought hens only had 1 color gene...

    SilverSilkie :

    There are 2 kind of color-genes, sex-linked and autosomal color-genes.
    In birds (as chickens are) males have 2 alleles of a sex-linked gene => S/S , females have only 1 allel of it => S/- (S stands for Silver).
    Of autosomale genes males and females have 2 alleles of it => c/c (c stands for colorless = recessive white) => I/I (I stands for Inhibitor = Dominant white).


    Think of sex-linked birds....the females get ONE allele of the color gene, where as males get TWO alleles - making them different and sex linked
    Autosomal means it affects both genders not one or the other. autosomal colors both sexes have 2 alleles

    Whites - you have recessive white and Dominant white. - which is c/c and I/I both males and females have this formula in their makeup. So he was saying she was mistaken about the hens having 1 color gene - white is autosomal meaning there are two and it is entirely possible for there to be leakage or another color bleeding through


    ***though it is a bit odd on a white bird except when they are actually paint atleast to MY understanding....
