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 .
Why does sex -- that is, sexual reproduction -- exist? In many ways, asexual reproduction is a better evolutionary strategy: Only one parent is required, and all of that parent's genes are passed on to its progeny.In sexual reproduction, only half of each parent's genes are passed to the next generation.hy does sex -- that is, sexual reproduction -- exist?
