Polymorphism with selection and genotype-dependent migration
Web27 nov. 2008 · The potential of maintaining multilocus polymorphism by migration-selection balance is studied. A large population of diploid individuals is distributed over finitely many demes connected by migration. Generations are discrete and nonoverlapping, selection may vary across demes, and loci are multiallelic. It is shown that if migration and … Web9 iul. 2024 · • Multiple niche polymorphism 7/9/2024 7:49 AM 5 6.

This balancing selection entails that the bacteria have different fitness in different vertebrate hosts.
