The dimensionality of genetic variation for wing shape in Drosophila melanogaster.

Evolution; international journal of organic evolution - 1 May 2005

Abstract excerpt

Absolute constraints are limitations on genetic variation that preclude evolutionary change in some aspect of the phenotype. Absolute constraints may reflect complete absence of variation, lack of genetic variation that extends the range of phenotypes beyond some limit, or lack of additive genetic variation. This last type of absolute constraint is bidirectional, because the mean cannot evolve to be larger or...
