An elderly woman with a history of coronary bypass comes in with severe, diffuse, abdominal pain. strangely, during your examination, the pain is not made worse by pressing on the abdomen. what do you suspect?

Ischemia is suspected in this case. If there’s history of bypass, it can be used as a clue to see if there is vascular narrowing elsewhere. Malingering is unlikely. However, neuropathic pain as seen in herpes zoster, would get worse with touch. 

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)
