Color Blindness: Sex-Linked Genetic Disorders
Color Blindness
Contrary to its name, color blindness does not involve any actual blindness. Color blindness, also known as color vision deficiency; is an incapacity to see a certain array of colors under average conditions of lighting. To have total color blindness of any sort of color is a very rare occurrence. This sex- linked genetic disorder is fairly common, more than 250 million people are affected with color blindness worldwide, and not deadly. My mother has a color blindness that hinders her ability to differentiate between certain shades of blue and green as well as not being able to see highlighter yellow.
There are multiple different kinds of color blindness, each effecting the individuals color spectrum in different ways. Most cases of color blindness are passed on through the X chromosome, making it easier for females to avoid it. “Men in contrary can not oversteer the defective chromosome, because they are carrying just one X chromosome.”(1) However, some kinds of color blindness are passed on through different chromosomes making it evenly heritable in both males and females. …show more content…
One for red, green, or blue light. If only one of these cones is defective it will alter the entire color spectrum for that person. “A color vision problem isn't always inherited. In some cases, a person can have an acquired color vision problem.”(2) Color blindness can also develop from aging, diseases such as glaucoma, or an injury in the eye. The majority of color blind people inherit it from their carrier mothers. “Inherited color blindness is caused by abnormal photo pigments. These color-detecting molecules are located in cone-shaped cells within the retina, called cone
