Digital differential expression analysis of c-Kit, Tyrp1, Tyr and Tyrp2 genes between black and white feather bulbs by RNA-Seq.

Note: Raw-B-1, Raw data of black feather bulb expression; Raw-W-1, Raw data of white feather bulb expression; TPM-B-1, Normalized expression level of genes in black plumage feather bulb library; TPM-W-1, Normalized expression level of genes in white plumage feather bulb library; Log₂ ratio(W-1/B-1), log₂(multiples of differentially expressed genes); P-value corresponds to differential gene expression test; FDR (False Discovery Rate) is used to determine the threshold P-value in multiple tests and analyses by manipulating the FDR value [27].
