1. I wish I could list any of those things on my resume!

2. To be ethical, I think "Biotransmogrification" should not be listed as her degree, even if she's studied it. It's not the name of her department or her specialization. Just because a person has studied something doesn't make it the name of her degree. But if "biotransmogrification" is an important skill for her employers to recognize, she should be sure list it underneath as a skill. For example
Hogwarts University, B.A. in Care of Magical Creatures, Specialization in Animal Transmogrification (2005)
- Performed honors research in animal and plant biotransmogrification with Prof. Hagrid, including....
That is, if she's been out of school a while. I have been, so any college activities would be listed under the college, because I've had several full-time jobs to list. If she has just graduated from school, she might just list her college above, and then under "Work Experience", list something like "Research Assistant, Biotransmogrification, 2009-2011" with duties below.

I actually have a similar situation in that I majored in a very broad inter-disciplinary major. At my school, students in this major had to either specialize in one of several tracks or create their own. I created my own, which was approved, and graduated after completing this work.
So my resume says something like: B.A., [Really Broad Major]; Specialization in [Narrower Subject Area]. And then the usual about the the honors and research etc. listed below.
