The scenario described is an example of the founder effect, where a new population is established by a very small number of individuals from a larger population, leading to a reduction in genetic variation and potential differences from the original population. This is a form of genetic drift, which refers to changes in the frequency of alleles in a population due to random events. Therefore, both genetic drift and the founder effect are correct in this context.
