Hope this helps u!! If u have any questions just message me & more than welcome to help u on Brainly.com :)
Explanation:
Humans, since they started taming wild cows, began artificially selecting the cows that produced more milk because this trait is desirous. Humans depended on milk for food. This artificial selection by humans ensured that traits for cows for more milk production were preserved in the population of tamed cows. Humans also went further to breed the cows that produced more milk leaving out those that didn’t. Just like natural selection, artificial selection favors the desired traits in a population.

If the DNA polymerase did nothing special when a mispairing occurred between an incoming deoxyribonucleoside triphosphate and the DNA template, the wrong nucleotide would often be incorporated into the new DNA chain, producing frequent mutations. The high fidelity of DNA replication, however, depends not only on complementary base-pairing but also on several “proofreading” mechanisms that act sequentially to correct any initial mispairing that might have occurred.
