    Hello!
    I was curious about a few (ok, pretty much ALL) bantam cochin colors...
    Which of the following (if any) breed true?

    Splash
    Lavendar
    Barred
    Wheaten
    Columbian
    Birchen
    Silver/Gold Laced

    Thanks! Jenn

    Yes all of those colors breed true when they are bred together (with a bird of the same color) Pretty much all cochin colors breed true except for the blues, with a blue blue cross you get Black, Blue and Splash. Since splash is the recessive color pattern all you can get is a splash when bred to another splash

    Quote:Splash is the homozygous state of the incompletely dominant blue gene; it is not recessivenot recessive.

    Whether or not a trait will breed true depends on whether it is present in a homozygous or heterozygous state. Genes that are homozygous will breed true when bred to another bird homozygous for the gene.

    Recessive genes generally are not apparent unless the bird carries no alternate allele, and thus by definition are homozygous and will breed true. Not so with dominant genes. With many dominant genes you cannot tell from appearance that the bird carries one copy versus two.

    From the list, the only ones that will always breed true are splash and lavender. They others may or may not, depending on the genetics of the specific birds involved.

    Excellent! Thanks so much for that explanation!
    Do all colors follow the same patterns of dominance, etc. throughout all the breeds or are color dominances more breed-specific?
    I ask because I found lots of information on colors but it would be for different breeds so I wasn't sure if it was the same for all!
    Thanks!

    Some varieties can be made using more than one genetic recipes. For example, Dominant white and splash can be exchanged in some varieties--for example, golden neck d'uccles can be made with either. In some countries one recipe for a variety may be the norm, while in another it is a slightly different recipe. For example, coronation susseX can be made with blue or with lavender. Buff is made in many different ways.

    There may be some differences between breeds, but I don;t think that is a huge factor--usually in those cases there are slightly different appearances as well as different genetic makeup.

    Thanks! I wasn't planning on mixing breeds or anything like that but sometimes I will run across color info on another breed and I was just curious if it would carry over to cochins!
    Thanks again!

    Barring is sex linked and a rooster needs to have two copies of the gene to breed true when crossed on a barred hen. He can look barred, but sorta "darker" and only have one copy of the gene, and if bred to a barred hen some of his offspring will not be barred.

    Quote:SONORA,
    You mentioned the goldneck, what would be the recipie to follow to get them? I have some projects I am working on, and was just curious. Hope to try for them too here soon.
    Thanks
