Answer:

Hello,

The answer to this question is 'A low-pitched parent and a high-pitched parent have a child with a medium-pitched voice.'

Explanation:

If voice pitch is an inherited trait, than low-pitch + high-pitch parent equals a medium pitch. You can't have a child with a low or high-pitched voice.
