Genetic diversity
Genetic diversity usually refers to the variation, or differences between, organisms at the DNA sequence level. This can be effected by natural or artificial (i.e. human) selection, mutation, recombination and other mechanisms.
Genetic diversity can be considered in many different ways, as discussed in later slides. This image shows the electrophoretic separation of a number of maize SSR markers all in one gel. Each lane represents a different maize line and the banding patterns identify allelic differences at each of the SSR loci.
