Is there anything called Genetic Anxiety? We inherit a lot from our ancestors, but how much the term Genetic Anxiety is true, and if it is true, can it be cured through the same ways(CBT, Exposure Therapy) or it has to be dealt with medications? Put otherwise, is it the medications only that can cure genetic anxiety?
Predisposition to anxiety can be inherited:


  Genetics and family history (e.g., parental anxiety) may predispose an
  individual for an increased risk of an anxiety disorder, but generally
  external stimuli will trigger its onset or exacerbation. Genetics
  accounts for about 43% variance in panic disorder and 28% in
  generalized anxiety disorder.


Treatment for anxiety disorders is not generally modified for genetic component, so therapies such as conditioning or CBT may be used regardless.  All anxiety disorders are assumed to involve an environment (non-genetic) trigger that can be addressed through therapy.

Research by Dias &amp; Ressler (2013) suggests that this is not necessarily the case in mice, where epigenetics alone (with no environmental trigger) can cause a purely genetic anxiety.  (Layman version)
