Homework Answers
From the given pedigree we can analyse that the disease shown here is autosomal recessive. As both the parents of individual 14 are affected there is 100% probability that the individual 14 will also have the disease or in other words, we can say that there is 0 probability for individual 14 not to have this disease.
So the correct option is E.
