What type of inheritance pattern describes color-blindness in humans?

Color blindness in humans is primarily caused by mutations in genes located on the X chromosome, which is why it is classified as a sex-linked recessive inheritance pattern. In this type of inheritance, the trait is associated with the sex chromosomes. Males, who have only one X chromosome (XY), are more frequently affected because they only need one copy of the mutated gene to express color blindness. In contrast, females (XX) require two copies of the mutated gene to express the condition, which makes it less common in females.

This pattern of inheritance highlights how traits linked to sex chromosomes can manifest differently between males and females, with males being more susceptible to certain genetic conditions due to their single X chromosome. Understanding the connection between color-blindness and its X-linked inheritance is crucial for comprehending genetic disorders and their transmission through generations.
