Is fear learned or genetic?

Fear is something long thought to be a learned response. Fear actually may be a partly inherited trait, one programmed into our genetic makeup, according to a study of twins.

Can fear be passed genetically?

Fear and anxiety are influenced by many genes; there is no such thing as a simple “fear” gene that is inherited from one generation to the next. The genes controlling neurotransmitters and their receptors are all present in several different forms in the general population.

Can fear run in families?

Research suggests that phobias can run in families, and that both genetic and environmental factors (nature and nurture) can contribute to developing a phobia.

What gene causes fear?

Further, the study found a connection between brain anatomy and the behavioural phenotype: the expression of the P4h-tm gene was especially high in the amygdala that plays a key role in controlling emotional reactions, including fear and anxiety. The P4h-tm gene accounts for the transcription of the P4H-TM protein.

Can stress change your DNA?

Exposure to stress can modify DNA methylation, which may alter gene expression and therefore contribute to disease phenotypes [15]. Early-life stress, such as childhood abuse and stress-related disorders, have lasting effects on methylation that may persist into adulthood [16,17,18,19].

Who is most likely to develop a phobia?

Your relatives. If someone in your family has a specific phobia or anxiety, you’re more likely to develop it, too. This could be an inherited tendency, or children may learn specific phobias by observing a family member’s phobic reaction to an object or a situation.
