 Abstract hybridization is a process whereby two or more distinct progenitor species combine their genetic material to form a new species. This process can lead to the formation of polyploid organisms, which are composed of multiple copies of each chromosome set from the original progenitors. The resulting genome contains two or more distinct subgenomes, which are derived from the different progenitors. In this study, researchers developed a method for identifying the subgenomes of a polyploid organism based on the presence of shared ancestral elements between the progenitors. This method was applied to several examples including tobacco, cotton, and brassica nappers. The results provided insights into the origins of these polyploids, revised the subgenome identities of strawberry, and provided perspective on subgenome dominance in high polyploids.
