What is how rare is brown hair and green eyes?

The combination of brown hair and green eyes is considered relatively uncommon, although not exceedingly rare. Both traits are determined by genetics, and the likelihood of inheriting both depends on the specific genetic makeup of one's parents.

• Green Eyes: Green eyes are less common than brown or blue eyes. Approximately 2% of the world's population has green eyes.
• Brown Hair: Brown hair is the most common hair color globally.

The rarity increases when the two are combined because it necessitates inheriting the genes for both traits, which is statistically less likely than inheriting each trait separately. While precise statistics are hard to pin down, it is safe to say that having both brown hair and green eyes makes you stand out in many populations.
