These genes do not directly cause the illness but can increase the likelihood of its development when combined with environmental factors or stressors.
B. Resilience genes are genetic variations that confer resilience or the ability to adapt and cope effectively with stress, adversity, or traumatic experiences.
C. The effect of vulnerability genes is influenced by various factors, including environmental influences, lifestyle factors, and gene-environment interactions.
