Since the father has normal color vision, he will pass his X chromosome with the normal vision allele to all of his daughters. The mother, being heterozygous, has one normal vision allele and one color blindness allele. Regardless of which allele the mother passes on, the presence of the father's normal allele ensures that all daughters will have at least one normal vision allele, making them have normal color vision.
