Schematic pattern of chromosomal ancestry resulting from a moderate number (~8–20) of generations since a two-way admixture event. Starting with the second generation, recombination produces chromosomal blocks of different continental ancestries. The present day admixed population has a varying extent of overall ancestry and has blocks of ancestry that vary in size both because of the random nature of recombination and because the original chromosomes have been subject to recombination for different numbers of generations.
