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).
The little boy who is blinded by the light: Toddler can only see in black and white due to rare eye disorder. 1  Harvey can only see black, white and shades of grey due to a rare vision deficiency.  His parents have just found out Harvey's younger sister also has the condition.
