Since the 20th century, the French-Canadian population has experienced significantly more intermixing with other ethnic groups, from many different origins. Nevertheless, while the French Canadians of Quebec today may be partly of other ancestries, the genetic contribution of the original French founders remains predominant, explaining about 90% of regional gene pools, while Acadians (descended from other French settlers in eastern Canada) account for 4% and British 2%, with Native American and other groups contributing less.[14][clarification needed]
