Five gene duplication types (DTs) were identified within each genome, including the whole genome duplications (WGD), tandem duplications (TD), proximal duplications (PD), transposed duplications (TRD), and scattered duplications (DSD). F. pennsylvanica genome sub database were established, recording the identified DTs and expected values, as well as the locations of their respective genomes for 26,187 genes.
