Duffy et al. 2004. Interactive effects of MC1R and OCA2 on melanoma risk phenotypes. All blue-eyed R/R individuals (Anm.: R steht für ein stark wirkendes Rothaarallel, im Gegensatz zu r. Beide sind aber rezessiv.) were in the fair/pale skin category but this decreased to 85.4% with fair/pale skin for brown/green-eyed R/R individuals, the remainder having medium skin color. This proportionate lightening in all genotypic groups when carrying both recessive blue-eyed b and red-hair R alleles indicates additive action of MC1R and BEY2/OCA2 loci on constitutive skin color.
Peter Frost: Why Do Europeans Have So Many Hair and Eye Colors? (Memento vom 2. Januar 2008 im Internet Archive) Yet skin color is weakly influenced by the different alleles for hair color or eye color, apart from the ones for red hair or blue eyes. Some have no effect at all on skin pigmentation.
