It would show that the Duchene muscular Dystrophy has a X Chromosome linked mode of inheritance because only males show the disease. So with the X Chromosomes in the body an affected father with this disease can pass it onto his daughter who then becomes a carrier however fathers cannot pass this disease onto their son. A father can either have a disease or not but he cannot be a carrier. Consequently, it shows that this disease is recessive with the change form of X Chromosomes carried by female. To create the Phenotype of the disease, females both X Chromosomes would have to take mutation. The recessive nature of the gene is distinctly demonstrated in Dianne’s pedigree diagram. This is because Dianne’s brother has this disease which inherited
