Region in chromosome 8 with the KIT gene. The region in chromosome 8 with KIT gene (SSC8: 43,550,236-43,602,062), which is responsible for dominant white color in pigs shows an increase in the number of copies in the European domestic individuals. A) Heatmap of the region containing the KIT gene. Blue color represents the diploid region where red color represents the region with copy number higher than 9. B) Location of the KIT gene in the porcine genome (extracted from Ensembl browser).
