Pummit Squares and x-linked recessive diseases?

one of the 4 is going to be a color blind dwarf the other one is going to be a dwarf one of the sons will be color blind and one of the sons will be normal it is important to note when you do these crosses that the father will p all his traits to his daughters while if a son's mother is a carrier half of the sons will be have the disease unless the father has the disease as well then the son will have a 100 % chance of having the disease why? because the male only has one x chromosome leaving it susceptible to any x linked disease hope that helps
