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).
Second opinion The above is not really accurate, color blindness can be caused by cataracts, Both my parents were unable to tell the difference between colors of things for many years after developing cataracts. Only the various shades of beige (Mother) or grey (Father) were apparent. Luckily this can now be cured by surgery. So the answer to this question must be :- Yes you can go color blind but there are possibilities for this to be reversed. 1 person found this useful.
