They produce more pheomelanin responsible for the red hair than eumelanin that produces shades of black and brown. Porcu, Eleonora Li, Yang For one to have red hair and blue eyes, the parents have to give them the MC1R recessive gene for red hair and the one for blue eyes. So depending on which genes the parents have the child has zero to 100% chance of getting this unique combination. Beekman, Marian If one parent is redheaded and the other isnt, the chances their child will have red hair is about 50 percent, though the shade of red may vary greatly. That's 13 million people, out of the 7.6 billion on Earth. We explored the effect of including principal components (PCs) on the genetic correlation between hair and eye color. Both hair and eye color are determined by gene variants present in the melanin pathway, including HERC2/OCA2, SLC24A4, and TYR (Candille et al., Reference Candille, Absher, Beleza, Bauchet, McEvoy and Garrison2012; Liu et al., Reference Liu, van Duijn, Vingerling, Hofman, Uitterlinden and Janssens2009; Sulem et al., Reference Sulem, Gudbjartsson, Stacey, Helgason, Rafnar and Magnusson2007; Zhang et al., Reference Zhang, Song, Liang, Nan, Zhang and Liu2013), though these genes may not explain all genetic variance in hair and eye color.
