Single nucleotide polymorphisms (SNPs) and insertions/deletion (IN/DEL) between 12 individuals from a corn-strain population (CL_1) and 12 individuals from a rice-strain population (RL_1) as well as in the maternal grandmothers (mgm) of BC_A and B (originating from these populations). Mgm = maternal grandmother; Sample name followed by Corn (= corn-strain) or Rice (= rice-strain); n.a. not available due to sequencing restrictions
