evolvability
Le Rouzic A & Carlborg Ö Evolutionary potential of hidden genetic variation. TREE 23:33-37.
- a substantial part of genetic variability can be buffered or released as the result of complex genetic interactions
- however, the impact of hidden genetic variation on phenotypic evolution is still not clear
- glossary
- buffering: the ability to decrease the amplitude of one or several other gene effects
- conversely, the ability to increase the amplitude of the genetic effects is called unbuffering
- canalization: selection-driven buffering
- capacitance: selection-driven unbuffering; possibly conditional to environmental factors
