On page 984 of this article, in Figure 1b, the homologous chromosomes were incorrectly shaded at the transition between meiosis I and meiosis II. A corrected version of the figure is shown below. The online versions of this article have been corrected. Figure 1

a | In mitosis, diploid cells replicate chromosomes during S phase and segregate sister chromatids during M phase, so that diploid daughter cells are produced. b | In meiosis, two chromosome-segregation phases, meiosis I and meiosis II, follow a single round of DNA replication during pre-meiotic S phase. During meiosis I, homologous chromosomes (shown in red and blue) are segregated to opposite poles. Sister chromatids segregate to opposite poles during meiosis II, which results in the formation of non-identical haploid gametes. Please note that the lengths of the cell-cycle stages are not drawn to scale.
