New work by scientists in the U.S. and China shows how a fertilized egg cell, or zygote, hits "reset" so that the newly formed embryo can develop according to its own genetic program. The study was published July 17 in Nature.

RIKEN researchers have shown how the genomic sorting that occurs during fertilization—the incorporation of genomic material from both parents and the elimination of excess maternal DNA from the egg—takes place in mice. ...

Not all species need sperm to fertilize an egg for sexual reproduction. Some species need sperm in order to induce completion of egg nucleus development, but then never use the sperm's DNA. I describe how this self-sexual ...

After double fertilization, zygotic activation occurs that initiates a new life cycle, followed by cell divisions, cell differentiation and organogenesis. During post-embryonic development, stem cells located in shoot apical ...
