Tonya's father does not have the dominant trait of webbed feet, and neither does Tonya's mother. What is the percentage that Tonya or any of her brothers of sisters will have webbed feet?

0%

Explanation:

For Tonya or her siblings to inherit one of their parents must have that allele. Since both her parents have the recessive phenotype that means neither of her parents carry the dominant gene so it would be impossible for Tonya or her siblings to have webbed feet.
