A hurricane devastates a population living on an island in the Atlantic Ocean, and only a few individuals survive. They then produce many children and several generations later the replenished population suffers from several inherited disorders that are very rare in other groups. A genetic event that explains this is

Population bottleneck

Explanation:

Population bottleneck can be defined as a sharp decrease in a population size which can be attributed to various environmental influences including fires, hurricane, famines etc.

This leads to loss of alleles and a small population. With a smaller population size, celebrities mutations can occur, producing several inherited disorders.
