Colorblindness **Description: ** **Color blindness (color vision deficiency) is a condition in which certain colors cannot be distinguished, and is mostly common due to an inherited condition. Red/green color blindness is the most common. However, yellow/blue color blindness does exist, it’s very rare. Total color blindness is only seeing shades of grey. This is extremely rare also. ** **Inheritance: **Color blindness is a trait controlled by a recessive allele on the X chromosome. It is usually inherited through a recessive trait which the mother has. Males, or the son, usually get this because they only have one X in their XY life. Females have two. (XX) **Symptoms: ** The symptoms vary depending on the type of color blindness the person has. The types of color blindness are: Monochromatism: Either none or one cones available. Dichromatism: Only two different cone types, the third one is missing. Anomalous Trichromatism: All three types are there, but with shifted peaks of sensitivity for one of them. This results in a smaller color spectrum. Triantopia: Missing or malfunctioning S-cone. (Blue) Deuterantopia: Missing or malfunctioning M-cone. (Green) Protanopia: Missing or malfunctioning L-cone.
