Evolvability and genetic constraint in Dalechampia blossoms: genetic correlations and conditional evolvability.

Abstract excerpt

The short-term evolvability of a character is closely related to its level of additive genetic variation. However, a large component of the variation in any one character may be pleiotropically linked to other characters under the influence of different selective factors. Therefore, the organization of the organism into quasi-independent modules may be an important prerequisite for evolvability. In this paper we...
