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 .
Genetic variation and diversity in a species is a good advantage. Asexual reproduction essentially clones itself. If something can kill one, it can kill them all. In sexual re â¦ production, there are many different sets of genes so what kills some may not kill all.ecause mutations in non-reproductive cells (aka somatic cells) are not heritable and therefore die with the individual in which they occurred. Only mutations that affect repr â¦ oductive cells (aka germ cells) are inherited by progeny and influence the genetic variation of a population over time.
