, Site Lin, Mbarek, Willemsen, Dolan, Fedko and you can Abdellaoui 2015) therefore the is a result of brand new GWAS to have eye colour was described from the Secondary question. I replicated the known genetic variations having attention colour including the HERC2 area to have brownish vision colour (ideal SNP: rs74940492, Or = 0.09, p = 5.4E-8) and blue/gray attention color (most readily useful SNP: rs2240202, Otherwise = , p = step 1.0E-47); TYR and you will SLC24A4 having bluish/grey (ideal SNPs: rs4904871, Otherwise = 0.71, p = 2.8E-13; rs67279079, Or = 0.70, p = 3.1E-11) and you will eco-friendly/hazel eyes color (best SNPs: rs4904871, Otherwise = 1.52, p = step 3.8E-20; rs67279079, Or = step one.forty-two, p = step three.6E-10). Of those recognized pigment hereditary versions, we understood that HERC2 have pleiotropic consequences toward blond, brown, black hair color and you can blue/gray, brownish eyes colour, and you may SLC24A4 features pleiotropic effects into blond, brown, dark tresses colour and you will bluish/grey and you may eco-friendly/hazel attention color.

The phenotypic association of eye and hair colors confirms the two traits to be strongly related in our sample (? 2 -test with 4 degrees of freedom gave a p value < 2.2?10 ?16 ): people with blond and red hair are likely to have blue/gray eyes while people with dark hair are more likely to have brown eyes. The counts and frequencies of the hair and eye color phenotypes for the 3,619 individuals (1,401 males; age: ± and 2,218 females; age: ±) are presented in Table 2(a), whereas Table 2(b) summarizes the information on the hair-eye color association from the much larger sample collected by Bolk ( Reference Bolk 1908), confirming the strong association in the Dutch population.

The fresh new hereditary correlations within tresses and you may vision colors are showed during the Dining table step 3. Right here, an equivalent relation is actually found as with the brand new phenotypic breakdown out of the information and knowledge, in which the genes connected with blonde tresses let you know an effective self-confident relationship which have blue/grey colored eyes and you can a bad correlation that have brown and eco-friendly coloured vision.
