A property professional with nearly 20 years experience of estate agency in Suffolk and North Essex. During that time I have carried out market appraisals on over 5000 residential properties and have helped over 1500 people successfully sell their home.
Therefore, a son from a color-blind mother (who receives the trait from his mother on the X-chromosome) will always be color-blind, regardless of the state of the father (who can only give his son a Y-chromosome).
Color blindness is a mutation on the X chromosome. If a woman is colorblind then all of her sons will be too since she passes on the X chromosome to them. As far as a daughter, both X chromosomes would have to be compromised as well because if one isnât then it can compensate for the other.
