In the version of this article originally published, there were errors in the text in the section titled ‘Production of disease-free embryos’. In “For instance, when both parents are carriers of recessive or dominant genetic disease, the number of embryos eligible for transfer to establish pregnancy is greatly reduced if avoiding affected and carrier embryos,” the text “or dominant negative” should be removed. Additionally, the sentence beginning “In cases in which one parent” should have the added text “or both parents have recessive mutations for the same disease”, reading “In cases in which one parent carries two dominant disease-causing alleles, or both parents have recessive mutations for the same disease, it would be impossible at present for them to produce a healthy, genetically related child.” The errors have been corrected in the HTML and PDF versions of the paper.
