Species	Genome size (Mb)	Total BDGPs	Total genes^a	Total BDGs/Total genes (%)	Unique BDGs	Redundant BDGs^b
Maize	2400	678	39656	3.4	1354	2
Sorghum	760	519	27609	3.76	1037	1
Rice	466	1874	55986	6.7	3740	8

^aTotal number of genes for each species.
^bIn cases where two BDGPs share one BDG, the shared BDG was counted twice in the total number of BDGs. Such BDGs are defined as redundant BDGs.
