The mitochondrial genomes of the surrogate and resurrected species share 99.9% identity.
What is this percentage identity?
This means that they are almost identical, with only a very small number of differences between them. These differences are likely due to mutations that occurred in the mitochondrial DNA of the surrogate species over time.
The high degree of identity between the mitochondrial genomes of the two species suggests that the resurrection process was successful in replicating the mitochondrial DNA of the extinct species. This is a significant achievement, as it suggests that it may be possible to resurrect other extinct species in the future.
