Among human populations Due to various migrations throughout human history, founder effects are somewhat common among humans in different times and places. The French Canadians of Quebec are a classical example of founder population. Over 150 years of French colonization, between 1608 and 1760, an estimated 8,500 pioneers married and left at least one descendant on the territory. Following the takeover of the colony by the British crown in 1760, immigration from France effectively stopped, but descendants of French settlers continued to grow in number mainly due to their high fertility rate. Intermarriage occurred mostly with the deported Acadians and migrants coming from the British Isles. Since the 20th century, immigration in Quebec and mixing of French Canadians involve people from all over the world. While the French Canadians of Quebec today may be partly of other ancestries, the genetic contribution of the original French founders is predominant, explaining about 90\% of regional gene pools, while Acadians (descended from other French settlers in eastern Canada) explain 4\% and British 2\%, with Native American and other groups contributing less.
