Raça em formação de galinhas de plumagem azul e ovos azuis - II. Teste de cruzamento

The data reported in this paper are in accordance with the hypothesis previously established (2) of the interaction of a main pair of alleles as controlling the inheritance of black, blue and blue-splashed plumage in chickens received from the State of Goias, Brazil. The black plumage is relatively uniform but the blue and blue splashed plumages indicate the action of other genes regulating the lack of uniformity.
