Web12 jun. 2024 · Species barriers, expressed as hybrid inviability and sterility, are often due to epistatic interactions between divergent loci from two lineages. Theoretical models indicate that the strength, direction, and complexity of these genetic interactions can strongly affect the expression of interspecific reproductive isolation and the rates at which new … Web17 sep. 2010 · If we assume that DM interactions occur between pairs of loci, the snowball hypothesis leads us to expect at least six (~2.4 2) times as many incompatibilities …

Web8 aug. 2007 · What Is a Plant Species? The definition of a species in plants has been a major impediment to botanical studies of speciation; botanists have often expressed doubt that plant species even exist, because of frequent reports of interspecific hybrids and because phenotypic variation in some plant groups does not assort readily into discrete … Webhybrid seed inviability (HSI) between recently diverged species suggest that HSI may play a fundamental role in plant speciation. Yet, a broader synthesis of HSI is needed to clarify its role in diversification. Here, I review the incidence and evolution of HSI. Hybrid seed inviability is common and evolves rapidly, suggesting that it may play an the son film inhalt
