What is the importance of DNA copying in reproduction? Why is variation beneficial to the species but not necessary for the individual? Explain.

answered-by-expert Expert Answer

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.
