Is color blindness a non disjunction?

Color blindness is not caused by non-disjunction. Instead, it is primarily a genetic condition linked to mutations on the X chromosome, affecting the photopigments in the retina responsible for color perception. Non-disjunction refers to the failure of chromosomes to separate properly during cell division, leading to conditions like Down syndrome. While color blindness can be inherited, it is not directly related to chromosomal abnormalities from non-disjunction.
