From: Large scale variation in DNA copy number in chicken breeds
CNV distribution across the chicken genome. Red bars indicate copy-number losses and blue bars copy-number gains. Bar length indicates the number of occurrence for a given CNV, divided into four groups: one contains ≥ 10 animals carrying this CNV; the second is ≥ 5 and <10 animals; the third is ≥ 2 and <5 and the last group has only one animal carrying this CNV.
