Introduction:

Color blindness is a disease characterized by inability of an individual to distinguish between different colors, mostly red and green. Males are more affected by this disease as the genes located for the diseased condition are located on the X gene. Since males have only one copy of X genes, they are more likely to be affected by this condition. Pedigree analysis is an approach to study inheritance of a particular train in humans. This is mainly useful when we need to study progeny data for several generations.
