 The dilution of the redhead gene in combination with white skin and blue eyes genes may not go extinct, but the EXPRESION of that combination could very well disappear! Any retard can do a thought experiment and see this. If you drop off a single white person with readhair in an african country of only black people population 1 billion. it is glaringly obvious that the EPRESSION of redhair with white skin and blue eyes will never be seen again. get a grip darn multicultural nazis!
