Description: The two genes that produce red and green light-sensitive proteins are located on the X chromosome. Mutations in these genes can cause color blindness. Color blindness is a common inherited sex-linked disorder that affects a person's ability to see or recognize certain colors.Eight to ten percent of all males and one half of a percent of all females are color-blind.Keywords: sensitive proteins,chromosome mutations,color blindness,chromosome x,x chromosome,sex linked disorder,genes,females,colors.utations in these genes can cause color blindness. Color blindness is a common inherited sex-linked disorder that affects a person's ability to see or recognize certain colors.
To create this model, EnChroma utilized the latest research on the genetics of color blindness and various anomalies related to photopigments, and linked these into a model where it gives the effect on how people with red or green color blindness perceive colors.
