Mice Inherit the Fears of Their Fathers

When it comes to inheritance, you’re getting more than just DNA. Life experiences – famine, stress, fear and even drug use – can all leave chemical marks on a person’s genetic material. This is often referred to as epigenetic (“above genetics”) modifications. Although these chemical add-ons don’t directly change the genetic code, they do alter the way genes are expressed and thus help drive long-lasting changes in brain function and behaviour.
Incredibly, these changes can be handed down through generations.
