The genetic consequences of hybridization

摘要: In the past decade, advances in genome sequencing have allowed researchers to uncover history of hybridization diverse groups species, including our own. Although field has made impressive progress documenting extent natural hybridization, both historical and recent, there are still many unanswered questions about its genetic evolutionary consequences. Recent work suggested that outcomes may be part predictable, but open nature selection on hybrids biological variables shape such hampered this area. We discuss what is known mechanisms drive changes ancestry after highlight major unresolved questions, their implications for predictability evolution hybridization.
