Your answer is Sex linked.
The reason for that is because when you have a dominant of (b) for color blind there is about %25 for color blindness and about %75 for normal eye sighting.
if it was co-dominance the orientation for color blindness would be higher in percentage with a less normal eyed percentage.
But, in this case your answer is Sex Linked.
Hope this helps!
