The chromatopsias are named for the colors seen: cyanopsia, blue; chloropsia, green; erythropsia, red; and xanthopsia, yellow.
Chromatopsia may be caused by drugs, disturbance of the optic centers, cataract extraction, or dazzling light.
Each chromosome consists of a double strand of DNA attached to proteins called histones.
The genes, which contain the genetic material that controls the inheritance of traits, are arranged in a linear pattern along the length of each DNA strand.
Each species has a characteristic number of chromosomes in each somatic cell. In humans, there are forty-six chromosomes, including twenty-two homologous pairs of autosomes and one pair of sex chromosomes.
One member of each pair is derived from each parent.
