Color blindness is the inability to see certain colors in the usual way; also called a color vision problem. A color vision problem can change your life. It makes it harder to learn and read, and you may not be able to have certain careers. Many young children get teased because of their condition, and few will believe what they are told. But people with color blindness can and have learned to make up for their problems seeing color. Color blindness affects a good amount of people, although exact proportions are different among ethnic groups. For example, in Australia it occurs in about eight percent of males and about point four percent of females. Isolated groups with a little gene pool sometimes produce high risks of color blindness, including the less usual types of this disorder. Examples include rural Finland, Hungary, and some of the Scottish islands. In the United States, about seven percent of the male population and less than one percent of the female population have color blindness. If you develop color vision problems when you normally have been able to see all the colors of the rainbow, then you should definitely visit your doctor. Sudden or gradual loss can indicate any number of underlying health problems, such as cataracts.

Fathers with this inherited form of red-green color blindness pass the X-linked gene to their daughters but not to their sons, because a son cannot receive X-linked genetic material from his father. A daughter who inherits the color-blindness gene from her father will be only a carrier unless her mother also has the color-blindness gene. If a daughter inherits the X-linked trait from both her father and her mother, then she...
