Founder effects in human populations
... Due to various migrations throughout human history, founder effects are somewhat common among humans in different times and places. The effective founder population of Quebec was only 2,600. After twelve to sixteen generations, with an eightyfold growth but only minimal gene dilution from intermarri ...
