Is that any different to comparable western series though? Western magic series often have that magic ability is hereditary. e.g. Harry Potter.
You mean Harry Potter's whos super special gene is knowing magic and nothing else? I mean you could bring up his Broomstick flying but all his friends had a special talent of their own, Harry just happened to have the more popular talent.
There is kind of a difference in "Being enabled" and being "Super special".
It is why I have absolutely no issue with Sakura from Card Captor Sakura. The whole point is she doesn't have any talents from her genes, she only has the power to wield the power.
As for Super Heroes... WOOSH! I can step into this field if you would like.
It is no where CLOSE to as thick and prolific as it is in Anime.
At least when Western media has someone who got where they were by training and practice instead of superior genes... They don't secretly give them super genes like Anime does

In fact has there been a Gundam main character (as in "The main character") yet who wasn't genetically predisposed to be amazing gundam pilot?
Naw there must be a few... Just not Gundam, Gundam 2, Gundam 3, Gundam Wing, Gundam Seed, Gundam Seed Destiny, Gundam Build Fighters, Gundam Build Fighters Try...
Edit: Or apparently Turn-a-Gundam either... I honestly thought that wouldn't be it.
Maybe that Gundam show that wasn't about Newtypes but a squad of ordinary soldiers in non-gundams.
