Correction to: Human Genetics https://doi.org/10.1007/s00439-019-02014-8
In the original article publication, there is an incorrect impression that Fig. 1 formed a formal Directed Acyclic Graph (DAG) by describing it as a causal model. However, it was not correct if interpreted in this way. The correct Fig. 1 is with a model that is correct when interpreted as a DAG, by making the differences between the model representation of ancestry and the true ancestry, which is always unobserved, explicit. We stress that there are other ways to introduce these biases, and it need not act through the separation between observed and true ancestry.
