Natural green eyes are caused by a combination of genetics and the amount of melanin in the iris. The gene for green eyes is recessive, meaning both parents must carry the gene for a child to have green eyes. Additionally, green eyes have a lower amount of melanin compared to other eye colors, which allows light to reflect off the iris and give the appearance of green.
Yes, green eyes are considered rare, making up only about 2% of the world's population. They are most commonly found in northern and central Europe, but can also be found in other parts of the world.
It is highly unlikely for someone's eye color to change from green to another color. While it is possible for eye color to change during childhood, once a person reaches adolescence, their eye color is typically set for life. However, certain factors such as lighting, clothing, and makeup can make green eyes appear to be a different shade.
Yes, there are several different shades of green eyes, including emerald green, olive green, and hazel green. The exact shade of green can vary based on the amount of melanin in the iris, as well as lighting and other environmental factors.
Yes, the gene for green eyes can be passed down through generations. However, because it is a recessive gene, both parents must carry the gene in order for a child to have green eyes. This means that even if both parents have green eyes, there is still a chance their child may not inherit the gene and have a different eye color.
