dominance

Kenney-Hunt JP & Cheverud JM 2009 Differential dominance of pleiotropic loci for mouse skeletal traits. Evolution 63:1845-1851.

• "differential dominance" describes the situation in which the dominance effects at a pleiotropic locus vary between traits
• even without any individual overdominant traits, some linear combination of traits will display overdominance at a locus displaying differential dominance
