2 Changes of Gene Frequency - the UC Davis Plant Breeding
2 Changes of Gene Frequency - the UC Davis Plant Breeding

... Mutation rates are generally very low — about 10 -5 or 10 -6 per generation for most loci in most organisms. This means that between about 1 in 100,000 and 1 in 1,000,000 gametes carry a newly mutated allele at any particular locus. With normal mutation rates, therefore, mutation alone can produce o ...

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.
