Study on the Relation between the Genotype and the Phenotype of Maroon, White and Yellow Quails' Feather Color and Its Application

Korean Longcheng line egg laying quails have been divided into three kinds of feather color.They are Longcheng maroon,Beijing white and Zhoukou Henan yellow feather. The White(m)×the maroon(f)→F 1:the maroon (m) and the white (f), and the yellow (m) ×the maroon (f)→F 1:the maroon (m) and the yellow (f).F 1 from two cross ways all could be autosexing.The yellow (m or f)× the white (m or f)→F 1 were also autosexing, but the yellow (m)×the white (f)→F 1:the maroon (m) and the yellow (f) while the white (m)×the yellow (f)→F 1:the maroon (m) and the white (f).It was proved that the maroon feather,the yellow feather and the white feather are all Sex linked inheitance by the cross experiments that we had done and others.The maroon and yellow feather constituted a pair relative characters determined by a couple of alleles(Y,y)in the Z chromosome.The maroon feather was caused by a dominat allele Y,and the yellow feather was caused by a recessive allele y. The white was caused by a recessive albino gene(b)in Z chromosome which recessive epistasis to Y and y.There is a gene(B)in Z chromosome of the maroon feather quails or yellow feather quails with which albinogene b is alleles.At the same time,we've discovered barred gene and white stain gene in the normal chromosome of the white feather quails line,and breed them into barred quails line,maroon or yellow and white quails line.
