Question

Quizplus · Accepted Answer

Color-deficient vision occurs when the red- or green-sensitive cones, or both, are not functioning correctly. This leads to difficulties distinguishing between colors and can result in a range of color vision deficiencies, such as red-green color blindness. Trichromatic visual processing refers to the normal functioning of three types of cone cells that allow for color perception, so A is incorrect. B and C are also incorrect as they are not related to the specific cause of color-deficient vision.
