genetics (and also, How does magic Work?) (and HIV too?)

As a High School student who just happens to be smart, I'll have to say that your conclusion that its polygenic seems to make the most sense. My guess is that everyone (muggles, wizards, maybe even salamanders) possess a certian amount of the various "Magic Genes." Lets, for the purpose of this post, call it, 1000. (I don't know if that is ridiculously high or low, but I suspect that most people won't care.) 1000 genes. 

The "scientific-sounding" explanation that I've made up for my yet-to-be-written fanfic is that Natural magic ability is caused by the ability to create a chemical that causes magical force to stick to it. (Like electrons) Wands serve the purpose of having ripping the energy from the hand to the outside world, by way of having in its core, a very magical animal's remnants (animals can possess the magic gene too.) Then the energy is forced forward by the wand, and aimed at the wanted target, and performs its charm.

Anyway, there are many many various different genes which produce various chemicals (or maybe they all order up the same chemical. That sounds like reality.) If a person has say, 100 active genes, they will have a reasonable amount of magic, but not enough to do anything, so as a result, they will be a muggle/squib (depending on who their parents are.) If someone has say, 986 active genes, they will be a very powerful witch or wizard.

It's a lovely "theory." Actually, I added something else. Its kind of off topic, but its all a part of my yet-to-be-written fanfic, and I really just add anything I think might remotely fit in to the story.

HIV is a magical illness. It is a virus which contains the "magic attracting" chemical, but because viruses are small, instead of attracting magic, magic attracts them. In wizards, the virius isn't very dangerous, because it stays close to the magic, and rarely attacks T cells, because they are stuck to "streams of magic" in the wizard's body. The virius is also not trasmitted through body fluids, because body fluids do not carry too much magic. But, the virius CAN be transmitted through curses. When someone performs a charm, the virius is carried along to the object to be charmed. If that object is a human, the human gets infected. If that human is not a wizard, they may get infected by the virius, because they don't have too much magic to ward the virius away from their T cells.

When Voldemort's Death Eaters rose in power, alot of people (muggles) were attacked. They got infected, and spread the disease. According to the Lexicon, the Death Eaters were in power in the seventies. If my really recent history is accurate, that was when AIDS started to start getting bad. My "theory" is all non-canonical bunk, but it still fits.
