Can a chicken that is p+/p+ R/r+ have what is considered a "bad rosecomb"? Does anyone have a picture of this? Linkage- Can someone please explain this to me. http://www.edelras.nl/chickengenetics/theory.html This is the website that I am looking at. How does a 10% linkage change the gametic ratios from 9:3:3:1 to 14:4:1:1 I am sure that there is an algebra equation that will explain it, but for the life of me, I am not getting it. I think that is it for now. Thanks!
