WebAug 13, 2024 · Animal pollinators directly affect plant gene flow by transferring pollen grains between individuals. Pollinators with restricted mobility are predicted to limit gene flow within and among populations, whereas pollinators that fly longer distances are likely to promote genetic cohesion. These predictions, however, remain poorly tested. WebAug 8, 2024 · The human body is made up of trillions of somatic cells with the capacity to divide into identical daughter cells facilitating organismal growth, repair, and response to the changing environment. This process is called “mitosis.” In gamete production, a different form of cell division occurs called “meiosis.” The outcome of meiosis is the creation of …

WebJul 21, 2024 · This genetic pattern is consistent with genetic cohesion, particularly among the typical floral morphs associated with continuous variation in floral color that are distributed across the range. In contrast, the C. purpurea species complex, which is characterized by divergence in floral color over narrow geographic clines, exhibits little ...
