Sex-linked traits are genetic characteristics determined by genes, which are located on sex chromosomes. Some examples are red-greenĀ colorblindness where it is found on the X chromosome, not theĀ Y, and hemophilia, a bleeding disorder the slows the blood clotting process. Just like colorblindness, it is found on the X chromosome.

Males are most susceptible to have these since they only have one X chromosome while females have two.
