Abstract excerpt

Mixed-ploidy species provide key insights into polyploid plant evolution, but the role of inter-cytotype gene-flow in their establishment and maintenance remains unclear due to the complex polysomic and heterogeneous genetic background of polyploids. Here, we established a mathematical model to describe inter-cytotype gene-flow patterns and validated it with migration rate data from the mixed-ploidy species...
