Be a kind human and me its urgent im freaking be a kind human and me its urgent: there is a small village in a mountain valley in spain whereumnumber of people are polydactyl (have more than five fingers or toes).onewhy does this trait tend to be passed on from generation to generation?

This trait is only passed down because of heredity. Think of it like this: In a Punnet Square, we can show H for trait of more than five fingers or toes, while h for trait of normal five fingers or toes. If two parents with the H trait is dominant, the offspring has a high likely chance to develop the same trait. Thus, most in this village have the polydactyl trait, the likelihood of the trait being passed on is high.
