Genes of colour blindness are the evidence of which given condition?

The X chromosome is home to the two genes that generate the red and green light-sensitive proteins. Color blindness may result from mutations in these genes. A frequent inherited sex-linked condition that impairs a person's ability to perceive or distinguish between particular colors is color blindness.

Genes of color blindness are evidence of a genetic condition. Color blindness is caused by mutations in genes that control the development of photopigments, which are molecules in the eye that detect light and allow us to see different colors. The most common type of color blindness is inherited in an X-linked recessive pattern, which means that the gene responsible is located on the X chromosome and only one copy of the mutated gene is needed to cause the condition in males (females are usually carriers).
