    The table lists individual genes, and then combinations of genes that create a specific pattern. A carot (^) indicates that the letters following are superscripted; something not always easily accomplished in all forums or other places. Towards the bottom it lists gene combinations that create certain phenotypes. For example, "Co, Pg, Ml render single lacing." This simply says that you need columbian, pattern and melonotic genes to have lacing on a bird. The reality is that you need two copies of each for correct lacing. Once copy of each gives a very heavy lacing, and if you have one of some and two of others, you will get a different pattern.

    Are there any specific things you do not understand?

    if you combine theseCo, Pg, Ml you get single lacing right

    yes most single laced birds carry the E locus gene ( allele) called brown and the female will express the phenotype better than a male. Males will not express single lacing in certain zones- the hackles, shoulder, back.

    Polish are single laced with a laced tail and carry the birchen allele and the dark brown gene. Single laced birds that have a heavy black tip on the end of the feather also carry dark brown- like in the sebright.

    Male birds that have a solid black tail only carry columbian as a restrictor while male birds that have a laced tail are birchen with dark brown added to the mix.

    non laced tail- eb/eb Co/Co Ml-Pg/Ml-Pg Ml, Pg and Db are linked genes that is why I have the - in the genotype.

    laced tail- ER/ER Co/Co Db-Ml-Pg/Db-Ml-Pg

    No lacing on extended black allele.

    The list shown here is used in a popup/alert in the new(er) chicken calculator to help explain the phenotype of a chicken produced.

    Few remarks. The "-" can be used to indicate the absence of a second sex chromosome in hens eg S/- or to indicate a linkage of genes as Tim did: Db-Ml-Pg/Db-Ml-Pg
