Table 1.

The mean and median expression of Z-linked and autosomal loci across various embryonic stages, head and BmN cells of Bombyx mori. The mean/median Z : A ratios (italicized) signify the relatively low expressed Z-linked genes to that of autosomal genes. The ratio values of less than 0.5, approximately 0.5 and greater than 0.5 correspond to less than half, half and more than half of average expression of Z-linked genes relative to that of autosomal genes.
