- 摘要:
- on, suggesting genetic variation at MHC loci is important for limiting virulence in a rapidly evolving pathogen and supports negative frequency-dependent selection

- 摘要:
- a negative frequency-dependent selection (a.k.a. ‘Red Queen’ dynamics). To sample P. ramosa, we experimentally infected a panel of Daphnia hosts with natural spore banks from the sediment
Data from: Mouth asymmetry in the textbook example of scale-eating cichlid fish is not a discrete dimorphism after all
