Figure 1.
Genomic organization of the OCA2 and HERC2 genes. OCA2 and HERC2 are very close to each other on human chromosome 15, with the 3′-end of HERC2 adjacent to the promoter region of the OCA2 gene. The red box in the chromosome ideogram indicates the position of the OCA2-HERC2 locus. Image from the UCSC Genome Browser (http://genome.ucsc.edu, accessed on 2 June 2023). At the bottom, the positions of the SNPs related to eye color, with details described in this section, are indicated by red arrows.
