Forum:Ways to get biotics?

So I'm wondering if there are any ways to get biotic abilities beyond just being born with them. I'm leaning on the side of the "yes" answer here for a few reasons. The first being that certain characters who have biotic abilities in the series don't seem to have a good explanation for having those abilities (Helena Blake anyone?). Another reason may just be me taking a gameplay element too seriously, but in ME2 and ME3 Shepard can obtain a biotic power from the intense training upgrade despite not being a member of a class with biotic abilities. You could also look at Randal Enzo, the protagonist of the Mass Effect: Infiltrator mobile game. He has biotic abilities despite being an obviously aging individual, and the phoenix operatives also may be running off the same kind of stuff as him. So does anyone know of any ways in the lore for this to make sense?
