color blindness is a x linked recessive disease and it occurs usually in males as they have only X chromosomes so any mutation is expressed as compared to females who have 2 X chromsomes for them to express both of the chromosomes have to carry the mutation.
female child will be a carrier but none of the children will have colour blindness
cross is shown with only one female X chromosome as both are normal so same will happen with other one

A colorblind woman marries a man who is not colorblind. What is the phenotypic ratio of the offspring?
