A newly cloned gene in corn will help explain how unusual interactions between a parent's genes can have lasting effects in future generations. The finding has implications for breeding better crop ...

IN THE 1860s, although nobody paid much attention at the time, a monk pottering around with pea plants established the basic rules of genetic inheritance. Gregor Mendel's laws of heredity say that ...

A study of spotted mice suggests that as well as contributing their usual cargoes of DNA, mammalian sperm and eggs might also trasmit heritable genetic information in the form of RNA. Mendel's laws of ...
