No, I'm not asking how to tie my shoes. I was just looking at pics of [email protected]@2four's gold-laced Polish birds, and was wondering...how does that coloration come about? Can anyone direct me to an explanation that can be understood by someone who is *not* a geneticist? I have a rudimentary working understanding of simple recessives, homo/heterozygosity, etc., from years of breeding horses and dogs, but nothing terribly complicated. Did the lacing pattern occur on its own at some point, in some form, and get selected for so that it was enhanced, or is it a result of combing several color/pattern traits over many generations?
