Answer:

1/2.

Explanation:

The autosomal dominant trait may en defined as the trait that can express itself even in the heterozygous condition and in the homozygous dominant condition as well.

Let the B allele is responisble for the roll tongue and b is recessive allele. The woman can roll the tongue and she must have the genotype Bb because her one parents is normal.

Thus, the answer is 1/2.
