X. D. Zhang, Wang, H. H., Zhang, C. X., Li, Q. H., Chen, X. H., and Lou, L. F., Analysis of skin color change and related gene expression after crossing of Dongxiang black chicken and ISA layer, vol. 14, pp. 11551-11561, 2015.

This study evaluated the effects of the autosomal domi­nant Fm gene in conjunction with the sex-linked Id gene on skin color and related gene expression. Ten Dongxiang black cocks were selected to build ten families by mating 60 individuals of ISA B-line layers. The skin color of the F1 generation was observed at different time points. At 126 days, 36 chickens were slaughtered, and gene expression of TYRP1, TYRP2, MC1R, and EDNRB in breast skin was assessed by quantitative RT-PCR.
