How do we measure genetic variation

WebData on variation is collected by surveying the population. This data can be described as either continuous variation or discontinuous variation. WebA study conducted by the National Science Foundation in 2007 found that genetic diversity (within species diversity) and biodiversity are dependent upon each other — i.e. that diversity within a species is necessary to maintain diversity among species, and vice versa.
