Red/green color blindness is an example of an inherited sex-linked trait. This means that the gene for color blindness is located on the X chromosome, which is one of the two sex chromosomes. Because males only have one X chromosome (inherited from their mother), they are more likely to express the trait if they inherit the gene. Females, on the other hand, have two X chromosomes and would need to inherit two copies of the gene to express the trait.
