Colour Blindness:
Cause: Colour blindness is a recessive sex-linked trait in which the eye fails to distinguish red and green colours. The gene for normal vision is dominant. The normal gene and its recessive alleles are carried by X-chromosome. In the female, colour blindness appears only when both the sex chromosomes carry the recessive gene (XcXc). The females have normal vision but function as a carrier if a single recessive gene for colour blindness is present (XXc). In males, the disease shows pseudodominance because Y-chromosomes of males do not carry any gene for colour vision.
It is inherited from mutations on the X-chromosome.
According to Mendelian genetics, when colour-blind father mates with carrier mother then the daughter is colour blind because there is a large probability that the daughter gets both the affected (XC) alleles.
However, when either father or mother is normal the daughter will not be colour blind.
Hence, the correct answer is 'Father is colour blind and mother is a carrier'.
