Answer:

A. 50 percent

Explanation:

Wilson disease is an autosomal recessive disease, it means that if a person has developed the disease, he must have two copies of the allele encoding disease. Suppose the allele of Wilson's disease is encoded by the letter T while normal allele is encoded by l.

Let's see what will happen if  a man with Wilson's disease marries a woman who is a carrier for Wilson's disease.

                               Father with disease X Carrier mother

P1:                                                  TT      x          TI

Gametes:                               T      : T        x         T  :    I

Offspring:                                TT:   TI   : TT:         TI


TT: Children with disease: 50%

TI:   Children who are carrier: 50%

So 50 % of the kids will have the disease while other 50% will be the carriers of disease to their next offspring.

Hope it helps!
