Genetic cohesion

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 …

WebIndeed, in such cases there is a sense in which low levels of gene flow, and selection, and mutations seem crucial causal factors of species cohesion. Traditional population genetic theory often overlooks such cases because it tends to focus on “weakly selected mutations” (ibid., p. 1343), rather than strongly selected ones.
