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?
No. Our personality is mostly not stored in our DNA but formed through our experiences as memories. Memories are stored in neurons and not in the DNA. When someone dies the information in the neurons vanishes. We have no way to capture the memories of a person and even less to implant them. So if someone dies there is no way to get that person back.
If we could clone a new person from that old DNA we would only get someone who looks roughly like the person you knew. Apart from that it’s a new and different person.
