Tree B would simply be a clone of Tree A…genetically identical but a different organism pretty much the moment you disconnected it from Tree A. Just because two things are genetically identical does not make them the same organism (see Jack and Finn Harries.)
Also, a genetically identical tree wouldn’t look the same as another tree as the shape of the tree is determined by environmental, not genetic, factors (as you say.)
So baby groot isn’t the same as original groot then, unless there is alien magic at work
This has also been something of a mystery to me. Like, Groot keeps his memories and consciousness when he’s regrown from a sprig…does that mean you have to find THE PERFECT RIGHT SPRIG that contains all of his Grootness? (This doesn’t seem to be the case if you’ve read the comics.)
But if that isn’t the case then, theoretically, you could regrow infinite Groots and make a whole Groot army…
SciShow explains the genetics — and physics — behind why blue eyes are blue, and what the future may be for the trait. Spoiler alert: Blue eyes aren’t really blue! SciShow explains!
Why Ferns Have More Chromosomes Than You
Chromosomes are fascinating little things, and today, Hank explains why more of them doesn’t mean more complex, and why different organisms have different numbers of chromosomes. The short answer: mistakes happen.

Twins X Twins = Twins?
At SciShow, we ask the tough questions. Today we explore the answer to the question “if identical twin brothers married identical twin sisters, would their offspring be identical?”
Elizabeth Blackburn: Great Minds
Hank brings us the story of Elizabeth Blackburn, the Nobel Prize-winning Australian woman who discovered telomeres and telomerase, and helped scientists begin to understand the process of aging at a genetic level.
Hank brings us the story of Gregor Mendel, the Austrian monk who, with the help of a garden full of pea plants, discovered the fundamental properties of inheritance and paved the way for modern genetics. He also gives us the dirt on a scientific scandal that has followed Mendel beyond the grave.
