Question 2
Twin sisters Leah and Lily know they have the genetics for heart disease. Both sisters like to exercise, but Lily also has a high-stress job and only sleeps four hours a night. Leah is a yoga instructor and eats a mostly vegetarian diet. The field of epigenetics would suggest __________.
◦ the stress in Lily's life will increase her cortisol levels and therefore decrease her chance of heart disease
◦ the environment has the ability to change gene expression, so both women can change their risk of developing heart disease
