From: Expression profiling of sexually dimorphic genes in the Japanese quail, Coturnix japonica

Expression patterns of nine clusters during gonadal sex differentiation. Between HH27 and HH31, gene expression levels increased in clusters 1, 2 and 3, remained constant in clusters 4, 5 and 6, and decreased in clusters 7, 8 and 9. Similarly, between HH31 and HH38, gene expression levels increased in clusters 1, 4 and 7, remained the same in clusters 2, 5 and 8, and decreased in clusters 3, 6 and 9. Blue and orange lines indicate genes related to gonadal differentiation in males (ZZ) and females (ZW), respectively.
