I have been poking the rules for GURPS magic again, getting more ideas for world setups.
So today I ended up trying to remember basic genetics, which I last paid any mind to, er, possibly 15 years ago. (It hasn't been quite that long since A levels... but I borked A levels.)
I was looking for a 'the magic comes back' urban fantasy background, and I thought with the recent population explosion simple maths might do it. If the chances of being a mage are one in a million then there's quite a lot of mages around by the end of the 20th century. Add in the new access to information on the internet, and the newest techniques for reading ancient books, plus the stuff like I saw in a documentary where texts that have been buried in the sand for centuries are being brought up in a more favorable political climate, and ordinary archaeological finds, and you have a possible critical mass of people who could not only find out about this stuff from newly reaquired texts but also have the talent to make it work.
Then I started thinking about the genetics of magery.

For a long time, nobody understood where magery came from. Very strong mages always had very strong mage children, everyone else had to guess. Nobody could tell who was a carrier, so magery could turn up in a family for no readily apparent reason.
Then there were persecutions. People with a little magic, but not enough to defend themselves, at best had to hide, at worst got killed. Magical communities got torched. Mostly the mages went away. A few Magery 3 families could be strong enough to avoid the hunters, and would have mage children, but only if they married other such families. Either there's strong ties between distant families, with any such tie increasing risk of discovery in that two can keep a secret if one is dead way, or there's isolated pockets of closely related people with an odd belief system. And they'd be trying to hide. Either way, magic goes back to being something secret that just turns up, sometimes, out of nowhere, when neither parent has it. This makes it difficult for mages to get any training, and leaves them very vulnerable.
Cue 21st century. In many parts of the world the persecution is over. And, finally, science has caught up: There's a test for the magery genes. Carriers can be identified, Mages confirmed genetically, and all the tricks of biotech are available.
Add that to the information explosion and boom, magic is back.
... with all the associated problems.
