    If someone could explain the genetics of spangling and lacing, including dominance and gender linkage if any, in simple terms, I would be forever grateful.

    Lacing is Co/Co, Ml/Ml, Pg/Pg - it can appear on two different E locus: e^b (partridge) and E^R (crowwing, birchen, brown-red)

    On E^R it also requires Db/Db (darkbrown) in order for the lacing to actually show up.


    Spangling is the same, however, there's another gene in play that someone else would better describe.



    There's no gender linkage/sex linkage.

    All genes are dominant.

    Quote:Spangling on E^R is is co+/co+, Db/Db, Pg/Pg, Ml/Ml.

    ETA: I am not positive but I think spangling on e^b is caused by the same genes as spangling on E^R.

    Quote:Lacing is also possible on Wheaten..


    Quote:Spangling on Er is Db/Db, Ml/Ml. Pg/Pg, no other gene at play



    Quote:Correct, but there is a linkage of about 10 cM that link Db-Ml-Pg preventing them to segregate independently

    Well, like I said. [​IMG] Not a spangling expert.



    I believe Spangling would work on Wheaten though, but lacing? I'd like to see that, personally. I've got some Wheaties with spangling, but not lacing. The best is a sort of double-laced, smudged effect that doesn't quite breed true.

    I have some Brabanters that should have spangling, but have lacing instead. I guess i just need to hatch and cull to get good spangling.

    Quote:Where'd you get them from? You'd be surprised how many hatchery based stock are actually just poor quality Polish. . .


    if yours aren't hatchery based, I'm sorry, I just mean to point out the fact that they are often indeed Polish with poor lacing and/or spangling and small crests

    I'd like to see lacing on wheatens too? Some birds involved in my laced projects are suspected to have eWh. Decent lacing is very much a challenge in these, especially ER/?eWh?.

    I got them from breeder in Texas. She got them from Ideal about ten years ago.

    Quote:You are having a problem with lacing in Birchen? I have two pullets that are finely laced throughout thier body with the exception of wing and tail primaries. they are young and soon to be mated back to thier father. Are you working LF or Bantam?
