It's not just facial features and character quirks that get passed down from generation to generation. Studies show that the same thing happens with values

In order for one generation to pass on its values to the next, two things are important. First of all, strong interactions between family members: the more time you spend with your family members, the more similar you will tend to be in your manner of thinking. The second important thing for "value transmission" was the social-cultural context. In other words, the type of society we live in tends to shape our beliefs.
