Answer: Males.
Step-by-step explanation:
Colorblindness is considerably more prevalent among men than women because it usually appears due to a genetic condition inherited through the x-chromosome. Somebody with both an x-chromosome and a y-chromosome simply requires one x-chromosome to be defective. On the other hand, if you have two x-chromosomes, both have to be defective to develop colorblindness. Since women tend to have two x-chromosomes (XX), and men only one (XY), men have more chances of having colorblindness.
