Growth Rate and Plumage Color in Chickens
Poultry Science, 1956 Abstract THE I-gene, an inhibitor of black (melanin) color, is currently being used in the development of the popular “dominant white” crossbreds for broiler production. Since none of the competitive meat strains posessed this gene, poultry breeders have introduced it into sire lines by crossbreeding.

Chimeric plumage coloration produced by ovarian transplantation in chickens
Poultry Science, 2013 Ovaries from Rhode Island Red donors were transplanted orthotopically into White Leghorn recipients. At maturation, recipients were mated with Rhode Island Red roosters to test the origin of their ovaries, using plumage coloration as a marker. A chick with chimeric plumage coloration was produced, indicating mechanisms that produce follicles with both ...
