Colour blindness is X-linked sex inheritance. For becoming colour blind, the female must have the allele for it in both her X-chromosomes and if only one X-chromosome of female possess allele for colour blind character she becomes the carrier. But males develop colour blindness when their X-chromosome has the allele for it. Thus males are more prone to colour blindness while females are carriers.
