Therefore, it is referred to as a sex-linked disease.People with hemophilia have severely reduced ability to clot their blood makingthem bleed easily from even the smallest injury. The recessive allele (the mutantallele) causes the disease, whereas the dominant allele does not. A woman withnormal blood but whose father had hemophilia ended up having a son and adaughter with a man who has hemophilia. (remember the birth sex of females is XXand the birth sex of males is XY). (2pts)(a) What is the probability that their son will have hemophilia?(b) What is the probability that their daughter will have hemophilia?(c) How would these probabilities be different if neither birth parent had hemophilia?
