This is The Rarest Hair and Eye Combination, According to Science

Green eyes are uncommon, sure, and it’s kinda cool that everyone with blue eyes is related, but your deep ash blonde hair doesn’t quite make the cut in terms of rare genetics.

The title of rarest hair color/eye color combination belongs to red haired folks with blue eyes. According to Medical Daily, both the blue eye trait and the red hair trait are recessive, so their likelihood of simultaneous appearance is pretty slim.

Red hair alone occurs with a frequency of one to two percent of the human population, while blue eyes occur in approximately 17 percent of the human population. Technically, that would mean 0.17 percent (or about 13 million people) of the world’s population have red hair and blue eyes. But since several factors play into the likelihood of that combination, that math is difficult to confirm. Either way, the combo is the rarest on the planet, and if you happen to have a red-hair, blue-eyed pal, don’t forget to share the fun fact.
