The vast majority of hereditary color blindness is inherited in a sex chromosome-linked recessive pattern. The inheritance pattern of color blindness can be divided into the following cases according to whether the parents are color blind or not and whether they carry the color blindness gene or not: 1. The father is color-blind and the mother has normal color vision and no color-blindness gene: the son is normal and the daughter does not have the disease but carries the color-blindness gene. 2. The father is colorblind and the mother has normal color vision with a colorblind gene: the son has a 50-50 chance of being colorblind, the daughter has a 50-50 chance of being colorblind, and the daughter has a 50-50 chance of being normal but carrying the gene for colorblindness. 3. Father colorblind, mother colorblind: both sons and daughters are colorblind. 4. Normal father, normal mother with normal color vision and no gene for color blindness: both children are normal and neither carries the gene for color blindness. 5. Normal father, normal mother with colorblind gene: half probability that the son is colorblind, half probability that the daughter is normal without colorblind gene, half probability that the daughter is normal with colorblind gene. 6. Normal father, colorblind mother: son develops the disease, daughter normal carries the colorblind gene. When abnormal color vision is found, it is recommended to seek medical treatment in time.
