Color blindness is an X-linked recessive trait. If the girl's father is colorblind, she has a higher chance of being colorblind as well. However, if the father is not colorblind but carries the recessive allele for colorblindness, the daughter can still be colorblind if the mother is a carrier or colorblind herself.

Color blindness is an X-linked recessive trait, which means that it is inherited through the X chromosome. Since the father determines the sex of the child, if the girl's father is colorblind, she has a higher chance of being colorblind as well. However, if the father is not colorblind but carries the recessive allele for colorblindness, the daughter can still be colorblind if the mother is a carrier or colorblind herself.
