Ploidy has little effect on timing early embryonic events in the haplo-diploid waspNasonia

The nucleocytoplasmic (N/C) ratio plays a prominent role in the maternal‐to‐zygotic transition (MZT) in many animals. The effect of the N/C ratio on cell‐cycle lengthening and zygotic genome activation (ZGA) has been studied extensively in Drosophila , where haploid embryos experience an additional division prior to completing cellularization and triploid embryos cellularize precociously by one division. In this study, we set out to understand...
