扩增片段长度多态性（AFLP）数据集已被用来构建邻居连接树，从单系起源的作物，如一粒小麦，大麦，二粒小麦已被推断。我们模拟了几个不同的多驯化的情况下，一个假想的谷类作物，并检查由此产生的驯化人口。模拟结果表明，驯化过程中的种群生物学方面可能会导致独立驯化的种群合并的方式，单系起源被错误地推断时，所产生的人口进行检查AFLP基因分型和邻居加入分析。这些结果对用这种方法来推断真实的作物的起源提出了质疑。
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 and neighbor-joining analysis. The results bring into question the use of this method to infer the origins of real crops.
