Jesse, what the fuck are you talking about?
People tend to shit on clones, but who else can come up with a large enough army to defend the Republic?
google chromosome crossing over
Holy genetic diversity
You didn’t factor recombination. Nobody ever receives any of their parents’ exact chromosomes, except the sex chromosomes from dad - each pair shuffles up the equivalent DNA between the 2 chromosomes, resulting in 2 chromosomes that are each a mix of both of that parent’s chromosomes of that pair, one of which is passed on to the child for each pair for each parent.
It’s unlikely to have ever happened.
2^42 is 25 times the total number of people ever born in all of history.
Also, twins aren’t identical copies either. Different fingerprint etc.
Fingerprints aren’t genetically coded, and clones wouldn’t have the same fingerprints, either.
I typically associate “clone” with “an exact copy”, with the same exact molecular layout and even thoughts. So a literal exact copy. Clones on a DNA basis, so something possible for years, would indeed be different in some details.
