Because they can, I’m sure they’ve done plenty of weird experiments.
I still don't understand why the Kaminoans would genetically alter Jango's DNA to make a female clone?? Why, and for what purpose??
They did say the original sample was deteriorating. Maybe the goal was to track done Alpha (Boba) and have him naturally procreate with Omega to make a super inbred truly pure DNA sample for the new ultimate clone??
