Several breeds have been developed—often by crossing a barred breed with a non-barred breed and then stabilizing the line—to achieve these results: ), which significantly lightens his down color

Because the barring gene is carried on the Z chromosome, a male chick receives two "doses" ( BBcap B cap B For instance, separate rearing can contribute to higher

Breeds like the Rhodebar, Welbar, and Wybar follow similar naming and genetic conventions. Autosexing vs. Sex-Linked Hybrids
