If Groot is anything like normal plantlife, Baby Groot would be identical to the original Groot in every conceivable way.
Wong believes that Baby Groot could’ve been created from the luminescent pollen, spores or seeds that Groot spreads towards the end of Guardians of the Galaxy Vol. 1.
A botanist and Guardians of the Galaxy fan has attempted to settle the debate over whether Baby Groot is Groot’s son.
The most likely possibility, as Wong sees it, is that Baby Groot is akin to a clone of the original Groot.
