Hair and eye color can be called unique “characteristics” of each person that determine his appearance and personality.
The combination of these two parameters can be varied, but some combinations are much less common than others.
What is the rarest combination of hair color and eye color?
Experts say that this “title” belongs to the combination of red hair and blue eyes.
The explanation is that both genes that affect hair and eye color are recessive, and the likelihood of a person inheriting both of them is extremely small.
For example, only 17% of people on Earth can boast of a heavenly gaze, although the rarest eye color is not blue, but green.
And there are even fewer redheads among the entire population of the planet - only 2%.
That's why there are so few blue-eyed red-haired people: only 12.7 million out of 7.5 billion.
Interestingly, statistically the probability of being struck by lightning (0.03% chance) is higher than meeting a person with red hair and blue eyes (0.017% chance).
