Are unicorns colour blind?
Can girls be colour blind?
Girls can be colour blind, but it is very uncommon. The colour blind gene occurs in the sex linked x-gene. Boys have only one x-gene. Girls have two. For a boy, if his x-gene is colour blind then he will be colour blind. This occurs about 1 in 20 boys. For a girl both her x-genes need to be colour blind genes. This occurs far less often, about 1 in 400 in theory. For a girl to be colour blind, her father MUST be colour blind and her mother must have at least one colour blind gene (which is, by luck, the one she gets). The mother may not be colour blind herself But ALL her sons will be colour blind. For a boy to be colour blind, the mother must carry the colour blind gene (which is, by luck, the one he gets). The mother may not be colour blind herself. His father contributes the y-gene and has no effect here.

Why are women rarely color blinded?
The colour blind gene is normally carried by females meaning that they are rarely affected by it. Men on the other hand are often effected and are very likely to be partially colour blind if their grandfather on their mothers side was also colour blind. However, some women can be colour blind if one of their parents is colour blind.

If a color blind male married a carrier of the color blindness female what would their offspring's genotype and phenotype be?
50% Answer Colourblindness is a sex-linked recessive mutation i.e. the mutation is carried on the X chromosome. If a colour blind man married a carrier woman they could produce a carrier daughter, a colour blind daughter, a normal son or a colour blind son. The probability of each phenotype occurring is 25%. If XC represents the normal allele for seeing colour and Xc represents the colour blind allele the genotypes of the possible offspring would be as follows: Carrier daughter = XCXc Colour blind daughter = XcXc Normal son = XCY Colour blind son = XcY This information is incorrect. In fact a woman can be color blind. My mother is color blind as are my brothers. My sister and I are not though we carry the gene. I have two daughters and one is color blind and the other is not color blind. The information I gave is not incorrect - I have included the possibility of that 'mating' producing a colour blind female child.
