Looking at the punnett square, which inheritance pattern is being shown? codominance sex-linked incomplete dominance

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!
