Answer:

The correct answer is - 100 %

Explanation:

As we know DMD or Duchenne Muscular Dystrophy is a sex-linked recessive disorder and according to the given pedigree, it is clear that Individual I-1 is a normal male and 1-2 is a female who has two defective genes of the disorder as if she had only one defective gene she would have a carrier for the disorder.

All gametes produced by both male and female would be -

Male - X and Y

Female - Xd and Xd

Therefore all the male offsprings or son will get one defective gene Xh from the mother for sure and a Y chromosome from the father. All daughters will also carry one gene Xh that is defective from the mother and normal X from the father but would be carriers for the disorder.

Why might it be more difficult to prepare a vaccine against noroviruses than against rotaviruses?

White raven [17]

Designing efficacious norovirus vaccines remains a major challenge due to several factors:

(1) the extreme genetic variability within the norovirus family and within genogroups

(2) the rapid evolution of antigenically dissimilar pandemic GII.4 norovirus strains

(3) the lack of lasting immunity upon natural exposure to noroviruses in at least a proportion of the population.
