You know when see a family member who you haven’t seen in a long time and they rave about how you look just like your parents. This is because of genetic traits. Everybody has genetic traits. When women have children each parent transfers or passes traits to the child which explains why children resemble their parents. But according to Laura Sander’s article, phenotypes aren’t the only things that are inherited by parents. Children can also inherit fear. This was discovered through an experiment done in mice by Brian Dias and Kerry Ressler. The results showed that a person’s traumatic experience can have a long lasting effect where it can be passed on to the next generation and on. The test involved mice receiving an electric shock every time the smelled orange blossoms. After the experiment was conducted, the offspring of these mice were afraid of smelling orange blossoms. The offspring were never exposed to the shock so it was very surprising that they experienced the same fear as their parents. The test changed the DNA structure of the gene in the shocked mice. It did not damage the gene, but caused a chemical switch that cause the gene to turn on or off. So if you ever noticed some similarities in fears with your parents, it’s probably because they passed on the trait to you.
