a western child raised using chopsticks from birth would they be better at using them than a child whose ancenstors are from that region?

Most likely

They would most likely have more practice if they use them all the time or even time to.time.

Maybe if the other child didn't grow up using them.

There is no gene for chopsticks, just like there is no gene for video games.

There isn't a competition to see whose baby uses chopsticks the best. 

There is no genetic memory for being able to use chopsticks.  Troll smarter, this is really pathetic.

WHAT region?  This is a silly question.

I think they would have about the same level of skill. If they use chopsticks correctly and the people around them use chopsticks then I'm assuming they will be good at using chopsticks.
