The individual gets the genetic code of a deceased person using that towards fresh stem cells (becomes a fetus) in which the newborn later on inherits the genetic traits that person but what remains a mystery is: will they also inherit the same behavior or mannerisms as that individual? Genes only carry attributes of a individual (appearance, hair color, eyes, etc). rather than their attitude (personality).
As from their genetic code, they look & resemble that person but will they act the same? Will they possess the same memories as that person? They may resmble someone you once knew however behave like a complete stranger, so it’s rather a gamble plus despite them looking like someone you know: is it really them or another stranger despite the very similar appearance and physical traits they have?
Is someone the same person after a TBI? No cloning needed to question what makes you, you, or them, them.
We know there are still some environmental differences, its how there can be identical twins with one gay and one straight. In the same sense we’d likely call the clone a stranger or “like a different person” rather than the original. They could share broad similarities but would inevitably have different experiences and thus be different.
