could a person who can curl their tongue(dominant) have parents who cannot curl their tongue? Explain your answer.

Answer:

Although unlikely, a person can have parents who cant’t curl their tongues while the person himself can. This may happen if the person’s grandparents had this dominant trait; it showed up in their children, but wasn’t expressed. In this way the parents may have carried the trait and passed it on to their child.
