Patterns, predictors, and consequence of dominance in hybrids

Kenneth Thompson, Mackenzie Urquhart-Cronish, Kenneth D. Whitney, Loren H. Rieseberg & Dolph Schluter
Compared to those of their parents, are the traits of first-generation (F1) hybrids typically intermediate, biased toward one parent, or mismatched for alternative parental phenotypes? And how does hybrid trait expression affect fitness? To address this empirical gap, we compiled data from 198 studies in which traits were measured in a common environment for two parent taxa and their F1 hybrids. We find that individual traits in F1s are, on average, halfway between the parental...
