A catastrophe or natural disaster event changed the population's size in the genetic drift experiment. Genetic drift is the term used to describe a population's allele frequencies changing randomly and without selection.
Small populations typically lose their genetic diversity faster than large populations do due to stochastic sampling error. This is because it is more likely that some gene variants will be lost in small populations due to chance. Genetic drift is an unpredictable process that can swiftly result in large population changes. Regularly tiny population numbers, drastic population size reductions known as "bottlenecks," and founder events where a new population is created from a small number of individuals are all factors that contribute to random drift.
So, in the genetic drift experiment, we may argue that a catastrophe or natural disaster event affected the size of the population.
