The most common cause of color blindness is an inherited fault in the development of one or more of the three sets of color sensing cones in the eye. Males are more likely to be color blind than females, as the genes responsible for the most common forms of color blindness are on the X chromosome. As females have two X chromosomes, a defect in one is typically compensated for by the other, while males only have one X chromosome.

Raw crabmeat should also be kept refrigerated and used within 24 hours. Thawed, previously frozen cooked crab should be used within the same day of purchase. Vacuum-packed crab can be stored in the refrigerator up to one month and used within four days of opening. Canned crab is good for six months. When using canned crabmeat in recipes, it is recommended that you pick over the meat.
