Premise Allopolyploidy—a hybridization‐induced whole‐genome duplication event—has been a major driver of plant diversification. The extent to which chromosomes pair with their proper homolog vs. with their homoeolog in allopolyploids varies across taxa, and methods to detect homoeologous gene flow (...
