Morphological diversity is generated by a continually shifting balance between variation and constraint. As modern evolutionary biology takes advantage of an enormous wealth of genetic and genomic ...

High levels of inherited variation are observed for most traits and in most populations. Variation is maintained partly by mutation and partly by a balance of selective forces; however, we do not know ...

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.

There are three key aspects to genetic disease associations: comprehensive variant discovery, accurate allele-frequency determination, and an understanding of the pattern of normal variation and its ...

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 ...
