Abstract:

Hybridization among diverging (interspecific or intraspecific) groups involves gene flow and genetic recombination. Increasingly, studies have shown that hybridization, a process of genetic exchanges, occurs widely in the divergence and unity of animals, plants, and microorganisms, and acts as an important mechanism for the formation and maintenance of biological diversity. The rapid development of high-throughput sequencing technology and the widespread application of genome-level techniques provides an unprecedented opportunity for us to further evaluate the universality and evolutionary significance of hybridization. However, selecting appropriate research techniques and strategies to detect the potential hybridization and evaluate its characteristics becomes a common question. In this review, we attempt to synthesize methods from phylogenetics and population genetics of the genomic era to provide biodiversity and evolutionary researchers a practical reference for testing hybridization.

Key words: genetic exchange, gene flow, biodiversity, phylogenetics, population genetics
