This suggests that the biological contribution to PTSD may be related to genetic factors, and that your friend may not have inherited a genetic predisposition for PTSD. It is important to note, however, that environmental factors can also play a role in the development of PTSD, so your friend may also have had protective environmental factors that helped them cope with their experiences. Option B is incorrect because environmental factors can play a significant role in behavior. Option C is incorrect because it suggests that inheritance is the only factor that determines behavior, which is not accurate. Option D is incorrect because it minimizes the experiences of soldiers in Iraq and does not consider the individual differences in how people respond to trauma.
