Angel is the foil to the Devil Gene. As to whether its genetically inherited like the Devil Gene I'm not sure but it seems that only the ladies of the Kazama family have it. Which is why Jin is seen as a "half-breed" of sorts.

I've read that the Devil Gene may actually have been from Kazumi Mishima(Kazuya's mom) and that Jinpachi has the power of the Devil but doesn't actually have the gene. I forgot what Harada said but he's been somewhat retconning Tekken back and forth.
