Cover for Genetic drift.

The present chapter describes another mechanism which can bring about random changes in gene frequencies, namely genetic drift. First, genetic drift is defined. Then, methods of measuring drift and ways to avoid drift are discussed. Lastly, the point is made that drift may lead to increased genetic ...

Cover for Introgression of cultivar beet genes to wild beet in the Ukraine.

One concern about the use of genetically modified plants is the unintentional spread of new genes from cultivated plants to their wild relatives causing unwanted effects. The ecological and genetic consequences of gene flow depend on the amount and direction of gene flow as well as on the fitness...
