if rebecca and rachel(jacob sisters) return to la push would they change into a werewolf??

Good question....but the reason they dont live in La Push is because one of them is married (Rachael) and lives in Hawaii and the other one goes to college (Rebecca)...she does come back and one of the オオカミ imprints on her (Paul I think).

I dont think the 狼, オオカミ gene was passed on to them ...maybe it had something to do with them being twins.

No first of all only Leah is the one with Gene to turn into Werewolf
Rachel has been imprinted on によって Paul.
Rebecca i think already has children when yo become a werewolf あなた cant have kids
Hope this helped !!

I think that the gene is only passed on every so often and that is why there are so few werewolves.
Also girl 狼男 aren't supposed to have kids
and one of the girls did.

It's rare for girls to turn into werewolves. The reason they stay away from La Push is because one of them is married and the other in college.

yes because they ave the gene
