Color blindedness is a sex-linked trait. if we could see the pedigree chart for several more generations of the family illustrated here, we would expect

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.
