Correction to: Nature Genetics https://doi.org/10.1038/s41588-018-0273-y, published online 19 November 2018.

In the version of this article initially published, the statement “there are no pan-genomes for any other animal or plant species” was incorrect. The statement has been corrected to “there are no reported pan-genomes for any other animal species, to our knowledge.” We thank David Edwards for bringing this error to our attention. The error has been corrected in the HTML and PDF versions of the article.
