Basic knowledge about the rate and range of mutation is central to our understanding of numerous evolutionary processes that include maintaining sexual reproduction and rates of molecular evolution.

Structural variants in the human genome include cytogenetically detectable and submicroscopic deletions, duplications, large-scale copy-number variants, inversions and translocations. The ability to ...

Concerns about biodiversity tend to focus on the loss of species from ecosystems, but a new study suggests that the loss of variation within species can also have important ecological consequences.

Variation is the differences between individuals of the same species, caused by genetic and environmental factors. Surveys into variation give data that are continuous, which means to come in a range, ...

Since no two things are exactly alike, variation affects us in every aspect of our lives. Surprisingly, most American managers still don't pay much attention to variation. When they do look at it, ...

A central part of quality management involves tracking, identifying and managing changes that occur in a system or process; these are variations. When changes are planned and executed well, the ...
