Fertilization often triggers the final step of haploidization of the female gamete genome. In this issue, Mori et al. (2021. J. Cell Biol.https://doi.org/10.1083/jcb.202012001) identify two successive actin-dependent mechanisms that delay fusion of maternal and paternal chromosomes, preventing inadvertent elimination of paternal chromosomes together with maternal ones.

防止非整倍体：新郎必须等到新娘准备好

受精通常会触发雌配子基因组单倍化的最后一步。在本期中，森等人。(2021. J. Cell Biol.https://doi.org/10.1083/jcb.202012001) 确定了两种连续的肌动蛋白依赖性机制，可延迟母本和父本染色体的融合，防止父本染色体与母本染色体一起被无意消除。
