WGD events, which may produce many deletions and inversions, variations in chromosome structure, and changes in large fragments on chromosomes promote biological evolution and species formation (Schmidt, Schindele and Puchta 2019). Complex genomic structures make the identification of homologous gene relationships difficult (Soltis et al. 2015). Recently, we counted the WGD event-related genes, which could reflect the influence of different events on genome expansion and diversification.
