Development: the maternal-zygotic transition revisited.
The handover from maternal to zygotic control has to be carefully orchestrated. In most animal embryos, maternal products drive early embryogenesis, and the genome of the zygote is only switched on later. However, in the nematode Ascaris the zygotic genome is never silent, and the maternal products are rapidly eliminated.
