Most of the DNA will be the same in all cells, but each cell will have
specific mutations (DNA changes) unique to the individual - either
having spontaneously occurred or having been picked up through the
process I described before. So in essence, each individual is unique
just like in humans, but the core DNA is the same - just like in
humans.

Humans have on average 7 unique mutations, most of which are mute,
which means they have no affect on the body.
