eye color的意思|示意

Eye color, or the color of one's irises, is an inherited trait influenced by several genes. Our genetic inheritance determines the specific hue and shade of our eye color.

The most common eye colors are brown, blue, and hazel. Brown is the most dominant eye color. People can also have gray, green, or even violet eyes. Most babies are born with blue eyes, but their eye color may change over the months and years following their birth.

The eye color gene is a recessive gene located on the X chromosome so it is carried along the maternal (female) line. The mother's eye color strongly influences the eye color of the children because the mother has two X chromosomes. The father's eye color has a lesser influence because he only has one X chromosome.

In general, we can determine eye color by looking at the eye of the person. If a person's irises are nearly black, they typically have black eyes. Dark brown eyes will appear even and similar in color, while hazel eyes are usually a mixture of brown, green, and yellow. Blue eyes, which can range from bright blue to dark blue, usually appear to have a starburst pattern.

Eye color is not only an interesting way to identify ourselves and other people, but it may also reveal something about our health. For example, a study conducted in 2013 found that adults with lighter eye colors are more sensitive to ultraviolet radiation and therefore more likely to develop certain types of skin cancer.
