    I want to produce a silver sussex with lavender instead of black markings. I understand how the lavender gene works, takes two copies ect ect. how ever I would like to know which pattern is dominate between the columbian of a coronation sussex and the pattern of a silver sussex. I don't know what you would call the silvers pattern, silver laced I suppose . the pattern is not very consistent in the birds, some feathers are all black some are laced, maybe birchin I'm not sure.
    any way should I use coronation sussex or a lav orp
    thanks

    There is no dominance in the patterns. There is only dominance among alleles or epistasis between genes. You can get what you want if you have a breeding regimen. More later have to go to work.

    Do you plan on crossing a coronation sussex with a silver sussex? If so

    coronation sussex X silver sussex = F1 silver sussex ( they will look more like silver sussex than coronation)

    Do a sibling cross or F1 cross = F2 some lavender silver sussex birds ( the birds will look similar to lavender silver sussex) - you will have to hatch chicks until you get a male and female

    Cross an F2 X F2= lavender silver sussex ( hatch chicks until you get good looking birds)

    Any chicks that have white/yellowish white down are wheaten and you do not want to use them for breeding. Only use chicks that have the down color of a silver sussex chick or a lavender chick.



    an alternative breeding regimen


    coronation sussex X silver sussex = F1 silver sussex ( they will look more like silver sussex than coronation)

    Do a sibling cross or F1 cross = F2 some lavender silver sussex birds ( the birds will look similar to lavender silver sussex) - you will have to hatch chicks until you get at least one lavender male or a few lavender females

    Back cross a lavender F2 ( looks similar to silver sussex) to a silver sussex= BC1 silver sussex ( they carry lavender)

    Cross BC1 x BC1= approximately 1 in four lavender silver sussex it depends on the genotype of the lavender F2
