title: AFLP data and the origins of domesticated crops.
abstract: Amplified fragment length polymorphism (AFLP) datasets have been used to construct neighbor-joining trees from which monophyletic origins for crops such as einkorn wheat, barley, and emmer wheat have been inferred. We simulated several different multiple domestication scenarios for an imaginary cereal crop and examined the resulting domesticated populations. The simulations showed that the population biology aspects of the domestication process can result in independently domesticated populations merging in such a way that a monophyletic origin is erroneously inferred when the resulting population is examined by AFLP genotyping a nd neighbor-joining analysis. The resultsbring into question the use of this method to infer the origins of real crops.
