Modeling additive and non-additive effects in a hybrid population using genome-wide genotyping: prediction accuracy implications.

abstract：:Invasive species are believed to spread through a process of stratified dispersal consisting of short-distance diffusive spread around established foci and human mediated long-distance jumps. Brazilian peppertree (Schinus terebinthifolius), native to South America, was introduced twice as an ornamental plant into Flor...
