Let D be the dominant allele and d be the recessive allele for Duchenne Muscular Dystrophy. a. The genotypes of the parents are: Mother - XDXd ; Father - XDY The genotype of the child is: XdY. b. XDXd x XDY There is 0% probability that another child will have Duchenne Muscular Dystrophy. c.If the couple was to have a daughter, There is 0% probability that she would have the disease. However 50% will be carrier. d. If the couple was to have a son, there is 0% probability that he would have the disease.XDXdXDXDXDXDXdYXDYXdY Solution Let D be the dominant allele and d be the recessive allele for Duchenne Muscular Dystrophy. a.
