From: The role of non-additive gene action on gene expression variation in plant domestication
Inheritance of transcript abundance unveils a relevant role of non-additive gene action in domesticated plants. A Distribution of the degree of dominance (k) across a series of genetic crosses including switchgrass, maize, chili pepper, sunflower, rice and Arabidopsis. |k|> 0.25 indicate non-additive inheritance. The color of circles indicates the category of the genetic cross. B Distribution of k for each category of genetic cross. Natural Selection: wild-wild; domestication: cultivated-wild; Inbreds: cultivated-cultivated. C Empirical cumulative distribution analysis revealed the switchgrass species evolving under natural selection are distinguishable from those evolving directional selection for both domestication (Kolmogorov–Smirnov: D = 0.21; p = 2.8E-14) and Inbreds (Kolmogorov–Smirnov: D = 0.28; p = 2.2E-16) genetic crosses
