Explanation:
Assuming the disorder is not sex linked, Charles is a carrier so he will be Ff.
His wife Elaine can be a carrier or not because her parents must have been both Ff
Possible F1 generation for her was FF, Ff, Ff and ff. She does not have the disease.
Therefore the total chance of her having FF was 1/3 whereas Ff will be 2/3
Probability of the kid having the disease will be calculated by;
(2/3×1/4) +(1/3×0)= 1/6
