I plan on majoring in genetics and minoring in either theology or psychology, or possibly both. All I know is that it will be some combination of the three. What job opportunities are out there with these subjects in mind?

Your best friend for this project is the Occupational Outlook Handbook, put out by the U.S. government every two years. Here's a link to the online version (paper version is at public libraries), and use the Search box at the top right of the home page -- Occupational Outlook Handbook, 2010-11 Edition. There's info on job training, job prospects, and working conditions for many, many jobs.

You could be a genetic counselor.
