Why is dna copying not beneficial to a individual
Asked by ganesangautam | 24th Aug, 2019, 06:30: AM
DNA copying is essential part of reproduction because it ensures that same blue print of the body design is maintained. Variation for the species is beneficial for adaptation and better survival. It may result in the formation of new species; however in an individual variation may not always be beneficial and may lead to disease or disorders, hence variation is beneficial for the species but not for an individual.
Variations are beneficial for the survival of the species. Populations of organisms fill well-defined places, or niches, in the ecosystem, using their ability to reproduce. However, niches can change because of reasons beyond the control of the organisms and could even wipe out the entire population. However, if some variations were to be present in a few individuals in these populations, there would be some chance for them to survive. For example - If there were a population of bacteria living in temperate waters and suppose the water temperature were to be increased by global warming. Most of these bacteria would die, but the few heat resistant variants would survive and grow further. Variation is thus useful for the survival of species over time.
