The value of twins and the importance of twin research

... WHY? If only genetic influences were important then we would expect the identical twins to be 100% similar as these twins share all of their DNA. In actuality the methods used to calculate the results and interpret them are much more complicated. Although researchers concentrate on twins in a city o ...

... Hybridization is widespread in plants but there are cases of hybridization in animals as well. Hybridization leads to important outcomes: 1.Generating novel genotypes. 2.Founding new evolutionary lineages. Fertile hybrids mediate gene flow from one species to another. •e.g., (Grant and Grant 2008). ...

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.
