[That Other Ninja]

I read a recent post by someone mentioning Shodaime and his bloodline limit, being Mokuton. Although we know the 1st Hokage's Mokuton wasn't a kekkei genkai but rather a unique trait specific to him, because his descendants are unable to use it (Tsunade), is it possible that the gene splicing done on Yamato/Tenzou by Orochimaru has infused this ability into his DNA, turning the ability into a bloodline limit for him and his future offspring?

I find it interesting that Haku's Hyoton was seen as a kekkei genkai, fusing water and wind to create ice but Shodaime's fusion of earth and water to create wood isn't.

Anyway, what are your thoughts? Personally I find Mokuton hella sexy. If it is officially announced in the manga as a bloodline trait then all the better for Yamato/Tenzou fans.
