This is an example of the founder effect, where a small group of individuals colonize a new area, carrying only a subset of the total genetic variation. In this case, the few Dutch settlers carried the gene for Huntington's disease, and this small, founding population became the source of a larger population of Afrikaners. As a result, Huntington's disease occurs at a relatively high frequency in this population.
