Imprinted Genes and Human Disease
Imprinted Genes and Human Disease

However, similar reasoning applies to any trait where changes in gene expression affect the fit‑ ness of matrilineal and patrilineal kin differently.26 In fact, many imprinted genes have effects on behavior that are difficult to interpret as straightforward extensions of parental conflict. Some of t ...

Many of these cytoplasmic determinants, like the two shown here, are unevenly distributed in the egg. After fertilization and mitotic division ...

History of genetic engineering

Genetic modification caused by human activity has been occurring since around 12,000 BC, when humans first began to domesticate organisms. Genetic engineering as the direct transfer of DNA from one organism to another was first accomplished by Herbert Boyer and Stanley Cohen in 1973. Advances have allowed scientists to manipulate and add genes to a variety of different organism and induce a range of different effects. Since 1976 the technology has been commercialised, with companies producing and selling genetically modified food and medicine.
