Figure 5From: Skin transcriptome profiles associated with coat color in sheepReal time PCR validation of differentially expressed genes in black versus white sheep skin. Abundance of target genes was normalized relative to abundance of â-actin gene. Bars in each panel represent the mean ± standard error (n = 3), * P < 0.05; ** P < 0.01; *** P < 0.001.Back to article page
