from 120 people? You wouldnt have a viable genetic diversity for long term survival. inbreeding would quickly become a thing, and i doubt you’d make it to even 100,000 before total collapse.
For long term survivability, you’d need like…a minimum of 5000 people, and even with 5k you’d have to have strict controls on who could have children with who, for decently long time.
