a Gene pairs with evolutionary relationship refer to two genes derived from tetraploid and one of its two diploid progenitors respectively, and which are at the same last-level branch in the phylogenetic tree and with the closest evolutionary distance
b Gene structure is to show whether the gene pair has the same intron/exon structure, the same is represented by S, and the difference is represented by D
