New payment models may ultimately prove to be the best option to systematically improve payment for primary care, but there is an uncertain track record with them, and the investment in the practice that is required makes for an uncertain and uneasy cost-benefit for primary care physicians.
Sexual reproduction is most advantageous , due to genetic variation . Meiosis plays an important part in sexual reproduction. During meioisis , after synapsis , genetic recombination occurs , dure to which we get varied gene pairs as well parental strands too .
Current hypotheses suggest that asexual reproduction may have short term benefits when rapid population growth is important or in stable environments, while sexual reproduction offers a net advantage by allowing more rapid generation of genetic diversity, allowing adaptation to changing environments.ragmentation is a form of asexual reproduction where a new organism grows from a fragment of the parent. Each fragment develops into a mature, fully grown individual. Fragmentation is seen in many organisms such as animals (some annelid worms [Which ones?] , turbellarians and sea stars), fungi, and plants.
