    It's described correctly later on, but this paragraph is inaccurate:

    The Brisbane twins are likely the result of one egg being fertilized by two sperm cells, resulting in three chromosomes. These three chromosomes were equally divided into two bunches of cells that then became two embryos.

    It should be three sets of chromosomes. The diagram shows how this was divided into three cells, but one set of cells was outcompeted. (My quick guess is that because it was from 2 sperm, it would have had improper genomic imprinting.)
