Is Creativity Hereditary?

So, I'm a writer. Obviously. :-) I also tend to participate in hobbies and activites that have a creative bent - I play piano (fairly decently) and guitar (not so decently, but I do a mean Stairway to Heaven). I sing (only at family parties when my uncle sets up his karaoke gear, or when I'm alone in the car). I can draw recognizable things (I'm about on the next level after stick figures). I love to play Rock Band.

My husband is an artist (he's WAY better than me). He's also written a few stories, just for fun (he's good), and he's the best plot generator-slash-evil-editor I've ever had the pleasure to work with.

Considering my husband and I are both creative people, was it inevitable that our son would turn out that way?

Our boy, now 13, loves to draw - and he's damned good at it. He's a fantastic drum player (and he kicks the crap out of Rock Band drums on Expert). He sings, but only when he thinks no one is listening (I am. HA!). And since I let him use my digital camera, he's shown quite a talent for directing and acting.

Here's a short movie he made with his cousin this weekend. They filmed it in about 20 minutes, and our son did all the editing, captioning and effects in about 30 minutes (including the time it took to reboot his computer and start over when it crashed on him in the middle of the first attempt). He's the shorter, dark-haired one (the blue-haired one is our cousin).

You tell me: does he get it from us? *G*
