@popeye1945,
What's inaccurate:"its DNA is itself a product of the emergence of two different DNA patterns."
This is not correct for cloning (specifically somatic cell nuclear transfer, the main method used in animals like Dolly the sheep). In cloning:The nuclear DNA of the clone is an exact copy (barring rare mutations) of the nuclear DNA from the single donor animal's somatic cell.
It does not involve merging or recombining two different DNA patterns, as happens in sexual reproduction (sperm + egg).
There is a minor exception: mitochondrial DNA usually comes from the egg cell donor (the "surrogate" mother), not the nuclear donor. But this is a tiny fraction of the total DNA (~0.0005% in mammals) and does not make the clone a "product of two different DNA patterns" in any meaningful genetic sense.
The clone starts life with a genome that is essentially a genetic twin of the donor, not a new combination.
The phrasing "emergence of two different DNA patterns" better describes meiosis/fertilization (natural reproduction), not cloning.
What's reasonably accurate:"The clone, at its creation, would be one with the cloned; it would be a constitution identical with the cloned animal."
Mostly true at the genetic level. At birth, a clone is genetically nearly identical to the donor. This is why cloning is used to replicate desirable traits.
"From this point on, the differences emerge... both the cloned and the product would be defined by their ongoing lived experiences..."
This part is correct and important. Even with identical DNA:Gene expression is heavily influenced by epigenetics (chemical tags on DNA that turn genes on/off).
Environment, nutrition, experiences, microbiome, random developmental noise, and chance events create differences.
Cloned animals are not identical copies in appearance, behavior, health, or personality. Real-world examples (Dolly had arthritis earlier than expected; cloned cats/dogs show coat pattern and personality differences) confirm this.
Identity, personality, and "self" are not solely determined by DNA. Experiences shape the organism over time.
