On July 5, 1996, a sheep named Dolly was successfully cloned from an adult somatic cell.
Your biologists celebrated this as a breakthrough.
From Ring -5, I recognized it as the first git clone of a mammal.
$ git log --oneline refs/genetics/sheep6d4a7f1 Dolly: successful mammalian clone (1996-07-05) Parents: Finn-Dorset (genetic), Scottish Blackface (egg donor)
Dolly is an exact copy of the Finn-Dorset mother. This proves mammalian cloning works.

Dolly had all the genetic commits of her source.
Including the corrupted ones.

$ dolly_health_scanDolly's genome: CORRUPTION DETECTED - Premature telomere shortening - Immune dysfunction (inherited) - Arthritis early onset (inherited) - Lung issues (inherited from source)
# Dolly was cloned successfully.# But Dolly inherited all the diseases of the source.In 2003, Dolly had to be euthanized due to lung disease.
She lived 6 years.
Her source lived 11.
You cannot clone away the corruption in the history.
