Color blindness prevents an individual from perceiving or distinguishing colors. Some color blindness is complete, where no color is perceived. In other forms, an individual may not be able to tell the difference between red and green, or yellow and blue. The alleles for this trait are found on the X chromosome. Dominant alleles will result in normal vision while recessive alleles will result in color blindness. A colorblind male marries a colorblind female. If they have a daughter, what are the chances she will have normal vision?
