The right answer is we would expect more males to be color blind.
Color blindness is a hereditary congenital anomaly associated with sex chromosome X.
For a man to be color-blind, it is only necessary for him to receive from his mother the chromosome X carrying this anomaly, whereas a woman can be a vector or color-blind. The fact that the allele involving daltonism is recessive means that if only one of the X chromosomes of the woman carries this anomaly, she will be a vector and not a colorblind like the man.
A female carrier is a woman who has the defect, which means she is not color blind, but can pass it on to her children. To be color-blind, both X chromosomes would have to be reached.
