What two primary negative genetic processes are accelerated when populations are restricted to small, disconnected fragments?

Answer

Genetic drift and inbreeding.

Isolation severely limits gene flow, which accelerates genetic drift (random fluctuation of gene variant frequencies) and increases the risk of inbreeding depression in small, disconnected populations.
