what is the importance of DNA copying in reproduction?why is variations beneficial to the species but not necessary to an individual? explain
Dear Student,
@ Ram: answer to your first question is nicely given by Knack.
I am providing you the answer for the second question.
Variations are beneficial to the species than individual because sometimes for a species, the environmental conditions change so drastically that their survival becomes difficult. Thus, these variants help in the survival of the species under those drastic conditions. However, all variations are not necessarily beneficial for the individual organisms. With subsequent generations, these variations keep on accumulating. Thus, they produce organisms that are more evolved than his ancestors.
@ Knack: Good answer!! We really appreciate your contribution to this forum. Keep posting!
Cheers!!
