Red hair is very rare. It occurs in 1-2% of people
Oh wow! I didn't know that, is that why red heads are sought after because they are exotic out of the population?
That's likely! People who have two copies of a recessive chromosome commonly have red hair.
I see! Are there other genetics rarities that interesting statistically?
When people have darker natural hair they have more hair follicles on their scalp.
Oh I did not know the either! I also that the sought after "dimples" people faces are actually a genetic disorder, but society has made the dimple a sought after facial feature!
Interesting! Dimples can appear and disappear over an extended period.
I did not know that either! Oh! People all start having flat feet as a baby and develop their arches over time, however some individuals never get the arch that other humans have.
