This is the evolutionary process known as genetic drift.
Nothing!
While mutation is a random event ( in no set numerical order ), natural selection is not!
genetic drift
Microevolution
Microevolution
Because of a small gene pool. small population generally equals small gene pool
population
changes in a population's gene pool.
There is no gene flow - APEX
chance changes in gene pool from generation to generation WITHOUT natural selection.

Genetic drift in small population results in fixation of a gene or loss of gene affecting only that particular population . It has no direct effect on diversity of organisms .
