Answer:

Color blindness or the inability to differentiate between certain color variations is more common in men because they have only one X chromosome. If defective M and L pigment genes reside on their single X chromosome, men will exhibit this trait. Women have two X chromosomes and therefore can be homozygous or heterozygous for the color blind trait. The phenomenon of X inactivation complicates the expression of color blindness in heterozygous females since only one X is functional and the other remains inactive as a Barr body. The inactivation of X chromosomes appears to be a random event.
