The correct statement is:

Traits that are similar in identical twins and not similar between unrelated people in the same environment are likely inherited.

This statement reflects the idea that if identical twins (who share the same genetic makeup) show similarity in a particular trait, while unrelated individuals (who share only the environment) do not, it suggests a strong genetic influence on that trait.
